Why would the power seat fuse in a 2000 Mazda 626 blow out continuously?

Answer . The most likely problem is a burned out motor. It's also possible that the wiring to the motor has been damaged and is shorting on the seat tracks.

What would cause the fuses to keep blowing for the turn signals?

Answer . A short somewhere in the wiring, an incorrectly installed bulb, damaged horn ring assembly, etc..

What would cause the fuse for a power seat to blow out in a 2000 Mazda 626?

Answer . Some fuses have a short life span most fuses you will have too replace once or twice i would just say has worn out and just needs replacing.

Why would the windshield wiper fuse blow as soon as the ignition switch is turned on in a 1993 Mazda 626 dx and how can this be fixed?

try disconnecting the wiper motor if problem still happens disconnect the wiper switch, if that does'nt work check your wiper control box, a fuse will only blow if there is too much current drawing on it or dead short to earth. try and follow the wires back from the wiper motor check for any damaged wires

What would cause the light fuse to continually blow on a 1994 Geo causing no interior or rear lights?

Answer . \nBy "rear lights" I assume you mean the tail lamps and not the stop lamps. My first response is to ask whether you've added any new equipment (radio, CD player, etc.) lately. You obviously have an overload on the circuit. Finding what's causing it (a direct short, too high a demand - i.e. new equipment exceeding the limits of the circuit, etc) requires a bit of investigation. If you leave the ignition off and all electronic equipment off (radio, etc.) and then install a replacement fuse, does it blow immediately? If it doesn't blow immediately, we would then want to know if you leave all your equipment off and turn on only the ignition, does it blow or does it remain intact? If it remains intact, try turning on various accessories (radio, apply brakes to illuminate the brake lights, dash lights, headlights, etc) one at a time and see which of these actions blows the fuse. When you've identified which piece of equipment is causing the fuse to blow you will have identified the circuit that need to be repaired. From there it's a matter of locating the overload (which may include a short circuit) on that system. A pinched wire shorted to the a frame member, corroded lamp bases, accumulated dirt/rust at electrical junction points; the list is endless.

What would cause a ecm b fuse on a 2000 gmc sierra to continually blow?

Depending on what engine is in the vehicle it may not have a distributor. If the engine is the 5.7L it does have a distributor. If you have the 4.8L or the 5.3L these engines do not have distributors. Does your fuel gauge work properly? A short in the internal fuel pump wiring will cause the ECM B fuse to blow. . on gmc's and chevy's there is a spot in the wiring harness that goes down the back of the engine block on the passenger side next to the distributor, this section of harness continuously rubs on the back of the block, more so if an intake manifold gasket was just replaced. it will rub a hole in the wiring loom and ground out there. check it out and see.

What causes the 80 amp main fuse on a 95 Mazda protege to blow?

Answer . A fuse of that size will only blow when something significant occurs. Has the vehicle been jump started with reverse polarity on the cables? Has the battery shorted or some other condition occurred that causes full current to go through the 80 amp fuse either from the battery or from the alternator? Has the diode plate in the alternator shorted? I don't know what all goes through the 80 amp fuse for that vehicle, but most other circuits will be fused at significantly lower amperage. I'd find a good vehicle manual with a schematic of the electrical system and find out the possible sources of such an energy drain. Good luck. If you discover anything that makes more questions feel free to comment on this question thread again. I'll mark this question to watch for further activity.

Why would taillights on a Mazda 626 not come on if the fuse is not blown?

Answer . If you mean the "BRAKE LIGHTS", it could be the switch, the turn signal switch, broken wires or bad connection in the wires or a faulty ground. If you mean the tail lights that come on with the headlights, it could be a bad headlight switch, burned out bulbs, bad wires or connection or a faulty ground.

What would cause the transmission to go in and out of overdrive on a 2000 Mazda 626?

Answer . \nit may be low transmition fluid pressure or you may have a solenoid messing up. have your vehicle scan for trouble codes. your vehicle's "T.C.M" should have an error code for that.

Why would a Mazda 626 blow cold air through the heater even after the engine is heated up?

Answer . \nPossibly low coolant level or blown heater core.....also check thermostat. Answer . CHECK COOLANT LEVEL FIRST. IF FULL THEN MOST LIKLY YOU NEED A THERMOSTAT.

Why would the audio fuse continue to blow if there is no short in the radio or CD changer?

impossible, there must be a short or it wouldn't blow. first check to see if anything is crossed, like anywhere as in behind the radio the neg and pos wires are switched. second, check the fuse panel for condensation or water leaks coming from anywhere. and lastly id suggest making sure you have the right amp fuse in there as a buddy of mine did that put a 10 amp fuse in a 20 amp slot and couldn't figure out why it was not working. if uve upgraded the speakers or audio system in anyway that creates a whole new mess of things, like ur aftermarket speakers for example are way too much for the stock built in amp for the dash. for example that but could be soemthing along those lines. for a quick fix try upping the amperage on the fuses til it doesnt blow but i don't recommend that for too long as it may or may not create other problems

What would cause a check engine light to come on on a 1997 Mazda 626 that has new O2 sensors exhaust filters fuel filter and convertor?

\n. \n Check Engine Light \n. \nMine was doing this same thing. It was the catalytic converter. It was about 250 for the part and 70 for labor. Runs great now and better gas miles!

What would cause the rear hatch lock-unlock not to work on a 1989 Mazda 626?

There is a little switch beside the light inside the hatch. When you open the hatch, look up at the inside back of the hatch lid, where the inside light is. The light itself has a switch to keep the light off, so that you can leave the hatch open without the light beeing on. Then, beside the light (attached to it, but off to the side), there is a small lever switch that enables /disables the interior lock / unlock switch. That's so you can give someone the valet key when they are working on the car, or just parking it. The valet key won't open the glove box or the hatch. It's a security feature. -- John

What would cause air to blow through the vents when nothing is on on a Mazda 626?

\n. \n Air Blowing Through Vents \n. \nIt is temperature control. Your car is wanting to breath or create a constant flow of air and will adjust itself with heat/cool or outside air. You should have an option to go manual and override its desire.

What would cause a 1996 Mazda 626 to a make metal tapping lifter noise?

Answer . metallic tapping that becomes faster as the engine speed increases indicates valve tapping. one or more of your valves clearances are misadjusted. to help you find out which one it is cut a small section of hose, put one end to your ear and place the other end on different spots along the rocker arm cover, where the sound is loudest is where the problem valve is. purchase a repair manual for your car for valve clearances and specific valve adjustment procedures.

What would cause the fuse to the tail lights and dash lights to blow on a 1993 Mazda 323 when the lights are turned on?

Answer . A couple possibilities: 1) the insulation from a wire is damaged and the wire is in contact with the frame of the vehicle. 2) A socket is damaged or the bulb is put in wrong or damaged. 3) if the vehicle has a trailer light plug, it could be wired wrong or damaged. 4) the light switch or relay (if it uses a relay) is faulty and must be replaced.. Another 2 posibilities are, if a new stereo has been fitted the earth for the stereo may have been connected to the illumination wire which tests as an earth when the park lights are off. To test this just unplug the stereo, replace the fuse and turn on the lights. If it stops isolate illumination wire and connect steroe to a proper earth. The other thing could be that illumination wire has been disconnected but not isolated properly and is shorting out behind radio.

What would cause your fuse to blow when you turn on your lights on your 1993 Mazda 323 the fuse to the tail lights on dash lights blow?

Answer 1 . I'm not sure I understand your question. I can't tell if you have one or two different fuses "blowing." The only thing which causes fuses to "blow" is a short circuit condition in the circuit which the fuse protects.\n. \nIF you have two different circuits blowing fuses, then you have at least two short circuit faults. j3h

What causes the engine to stall when you press the brakes on 1995 Mazda 626?

Answer . Does it do it in park, or Drive or Reverse?\nIs it an automatic, or manual car?\nI'm assuming Automatic but could be wrong.\n. \nCheck Idle speed. \nSet to specifications in Service manual.\n. \nA vacuum leak can cause stalling.\nWhen using your brakes you pull even more vacuum off the engine.\nListen around your engine for a sucking sound run your hand around the vacuum lines and hoses.\nGently push and bend the hoses a little looking for cracks and wear.\nReplace any hoses that are cracked.\nA vacuum advance unit on the older distributor driven cars were causes as well.\nIf you have a vacuum advance unit on this car it may be faulty.\nTo check any unit that has vacuum running to it, disconnect it, put a golf tee in the end of the hose and test for change.\nHave a friend help you while you accelerate the engine have them press the brake pedal.\nListen carefully checking for leakage in the brake booster unit.\nIf you find no vacuum leakage, a throttle position sensor has been known to cause stalling as well.\nWithout more information I am guessing mostly.\n. \nPosting the Model, type, and engine size, transmission type does help in diagnoses.

What would cause a 30A engine control fuse to keep blowing on a 1993 Jeep Grand Cherokee Ltd?

Answer . There is a dead short somewhere. If there has not been any damage to the vehicle to cause a possible short it is a process of elimination. Battery cable touching frame? Disconnect the heavy wire from the back of the alternator and see if it blows. Amp for the radio? What doesn't work when the fuse is blown? With the key in the on position you should be able to narrow down the posibilities.

What would cause the turn signal fuse to keep blowing?

Could be there is a short to ground somewhere in the system or thecircuit is overloaded with extras. If you have a trailer plug inback take a good look at that area for a short.

What could be causing the fuse to the dash and headlights to continue blowing?

Answer . You have a short somewhere in the circuit. Trace the wires out paying close attention to where the wires go thru firewall, around sharp edges. Look for melted insulation or burnt areas. Always put manufacturers rated fuse , don't put the biggest one you can find in it to stop it from blowing or you will definitely find the problem, ie electrical fire.

What causes the Mazda Millenia Engine Fuse to short out blown fuse?

The trick is to check for a short somewhere in the electrical system. Here is what I found on my MPV, maybe it will help: check the wiring inside the vehicle on the passenger side under the dashboard near the fire wall. The on-board computer (i.e., metallic box mounted right above where the passenger's feet would be) has a large number of wires going into it. We found a wiring union about 5 inches from the computer that was unshielded. It was shorting out against the metal case of the computer periodically, blowing the engine fuse. Use electrical tape to insulate the connection. (If I remember correctly, the wires were black and white.)

Would a bad voltage reulator cause fuses to blow?

Years ago this problem was very frequent. Charging systems are far more advanced now.If the voltage regulator is bad, I can see that the higher than expected voltage increased the current, causing the fusing to blow out. However, if the voltage regulator is good (if the voltage regulator is on the alternator, one would hope it is good), then the voltage should be ok. So the possible problems include: 1) Bad voltage regulator, leading to too high a voltage, causing the fuses to blow out. 2) The mechanic used the wrong fuses. 3) There is a short circuit in the circuits controlled by the fuses. It should be easy to test for [1] with a voltmeter and [2] by checking the fuse ratings against the ones in the owner's manual. If it is [3], some needs to go and figure out where the short(s) is.

How do you know which engine you have in your Mazda 626 2.5l?

What would cause the dashlights and taillights fuse on a 1995 Mazda MX-6 to blow even when the fuse was just replaced?

Answer 1 . A conductor [wire] is capable of carrying only a limited amount of electrical current [measured in Amps] without overheating, which could result in damage to the insulation on the wire, or in the worst case, a fire!. A fuse [or circuit breaker] is a device designed to limit the flow of an excess, or dangerous amount of current. It works by "blowing" out, or melting a fine wire within the fuse. When a fuse blows, it "opens" the circuit, thus preventing the flow of current and thus protecting the wire(s) in the circuit in which it is installed.. IF you are blowing newly installed fuses as soon as they are installed, or power to that circuit is turned on, then that is an indication that there is a "short circuit" somewhere in that circuit.. A short circuit is a condition where an electrically energized conductor has come in contact with a "ground" [a ground wire, the vehicle frame or any metallic part of the vehicle which is in contact with the negative terminal of the battery].. To prevent the problem of repeatedly blowing newly installed fuses, it is necessary that the ground condition be found, and corrected [removed], before attempting to install another new fuse. Short circuits can damage or destroy expensive electrical devices, the wiring system of a vehicle, or cause a fire which could destroy the vehicle, and seriously injure or kill someone.. Do-it-yourselfers should not attempt to correct short circuit porblems without knowledgible help, and it is best to have that work done by a qualified automotive electronics technician.

What would cause the cooling fan to constantly run on a Mazda 626 1999 model?

\nAnswer: If you mean your radiator cooling fan, it most likely is a grounded or shorted circuit from the "cooling fan sensor" (internal) or a pinched wire. Depends on when it happened: was there any work done prior to this happening? IF not, then the sensor is most likely the issue. In this case, once you find it (normally the sensor is screwed into the bottom of the radiator), unplug one of the wires (or remove the connector) and see if the cooling fan continues to run, if the fan turns off, then replace the sensor.

What causes the ac fuses to keep blowing in a 1996 Mazda 626dx?

Fuses blow because of a bad wire, bad switch, or bad motor. First, check the wiring. Look for a bad wire. Shake the switches and solenoids, etc. See if one rattles. Start it up and see if a motor acts bad. Check the fluid level. It may be running low on refrigerant and the motor might be heating up. There are a whole lot of things.

What causes the main engine fuse 80A to keep blowing?

Fuses That "Blow" Repeatedly .

What would cause multiple fuses to blow?

A fuse always blows for excessive current. Either the device it is protecting is going bad and drawing excessive current, or you have a short in the wiring (or device). Are you using the right value of fuse ? If this involves your brake lights or turn signals, it could be the bulb itself. Quite often the filaments short internally inside the bulb when they blow, and short the brake wiring to the turn signal wiring. Check for a bulb with a white residue inside it. If you find one, replace it. It will probably have two contacts in the base, one for each filament.

What would have caused your 40 amp fuse to blow?

What Causes Any Fuse to "Blow?" The cause is what fuses were invented and are used for : to detect and protect against SHORT CIRCUIT conditions, and /or CIRCUIT OVERLOAD conditions.

What would cause fuses to blow continuously in a 1998 dodge stratus?

Any of them my 1986 BMW had a wire that was arking and was blowing 2-3 diffrent fuses at a time could be bad wiring Excessive current from most anywhere. What fuse, look at the fuse access cover or the book to see what circuit (horn, lighter,lights etc) to see which fuse is opening (most folks say blown) its actually a melted strip of wire where the current rating (10 amp, 20 amp etc)has be exceeded. Don't forget to look in the fuse panel under the hood also!

What would cause an inline fuel pump to run continuously in a Mazda Navajo AFTER the engine is turned off - Runs all night?

Could be a "sticking" mechanical relay / if doesn't turn off or drop out the circuit, when it should. Power is flowing to the electric pump. In a fuel injection circuit the fuel pump turns on with the ingnition switch and runs until it reaches a pressure: cutoff point (where it stops) or set point, if the fuel injectors are not leaking fuel. Some systems use a transfer pump or lift pump besides the fuel injector "feed" Some systems of course have a return from the fuel rail back to the tank this also cools the fuel and makes for an easier starting warm engine engine. You need to have some one look at that model's electrical schematic. Yes, that means getting the Vehicle Identification Number (VIN) and a trip to the dealers or library. This will be better than the general auto parts manuals. You will get spacific locations and I.D. the places relays could be hidden. (If you poor boy it) You could cut the wire: put in an on/off switch

What would cause the dome lamp fuse to blow?

Old fuses, or too small a rating, or poor connections at the fuse may cause it to blow once, but not again. Dome lights run Hot, so, burnt insulation from the heat can cause a short in the dome light housing. Also a pinched wire. I had to put heat shrink over the connections in my '80 Chevy's dome lite, as the insulation was black and about to go. Bending the repaired wires away from the bulb helps it from burning again, too. Be sure to close all doors and let lamp Cool before you remove it--they get Real Hot. Wipe it with alcohol after you reinsert it to keep finger oils from causing hot spots that will cause the bulb to crack and fail.

What would cause 1999 Mazda 626 not have any power with fully charged battery?

The battery has nothing to do with the power of the engine. Now if you are referring to starting power then some batteries can show a full charge and still not be able to start the engine. Remove the battery and have it tested for free at almost any auto parts store that sells batteries or Walmart.
