The blower motor is failing and will need replaced.

Could be burning it at such a slow rate not showing smoke Could be leaking on hot part of engine and burning off How much is it consuming?


AnswerFind the location of the fuse that is burning. And check to see if the fuse that is burned out is the correct wattage for that spot.


go to a checker, autozone or auto parts store they will retrieve the codes that turned ur check engine light on, and give u tips to fix it or just re list them on here i will help you find the root cause.



The component used to protect a LED from burning up is called a resistor.


Itr only takes a small amount of oil to get some smoke, white smoke is coolant, gray smoke would be oil, and black smoke would be fuel.


To fix this on my car I thought I needed a new starter but when I went to take the starter out the bolt holding the positive cable on the starter wasn't very tight so I thought maybe that's it. Well that was the problem so I took back the $160 starter and the fuse never blew again.


If your batteries were in series the total voltage would be 6 volts, and it the bulbs were in series you would need a resistor to keep them from burning out. In order to know how many ohms the resistor would need to be you would have to know the wattage of the bulbs, or the resistance of the bulbs. If you don't know the best thing to do is use a variable resistor. Then you can adjust it or the brightness that you want.


You'll probably smell that burning smell if your gas is burning right, try putting about a cup of sugar into your gas tank as a catalyst.WRONG!! Do not put sugar in your gas tank! This will likely ruin your engine!!


Keep in mind if the new resistor burns out in a short time, next time replace the blower motor also. A failing blower motor can be the cause of burning out the resistor.

MSN Autos reported the blower motor problem as a resistor failure on the blower motor. In plain English, this means that the resistor on the fan motor which tells it to slow down to a lower speed than "max" is burnt out and no longer completes the circuit. If your heater is on & the fan isn't blowing, it's like a toaster in your dash, with no toast in it. It'll just smell like burning. Apparently it's a cheap fix. The resistor just has to be replaced.

The only dangers that might arise from driving a vehicle with a failing power steering pump is burning up/breaking the belt that is driving the pump IF and ONLY IF the pump seizes up. The other problem you might have is the increased effort to steer the car. As long as the increased effort while driving is not a problem you can at least drive it to a service station to get it repaired.


They get noisy, squeal and vibrate. Also if you keep burning out the blower motor resistor, that is a sign the blower motor is on its way out.


The filament of a light bulb isn't like a resistor ... it is a resistor. The only difference from the ones on circuit boards is the it's designed to operate at a much higher temperature. So hot that it glows. The glass envelope is there to prevent oxygen from getting in and promptly burning it. When the filament becomes too hot it breaks breaking the current that was lighting it in the first place. That is why the light bulb "burns" out.


those trucks had common problem of the blower motor resistor going bad or burning out and it would only work on high speed. the resistor is located under the passenger side dash by the blower motor. hope this helps


One way to look at the purpose of a resistor is as a device built to dissipateelectrical energy. Some (but usually not all) of the energy of the current througha circuit is always dissipated when it flows through a resistor. The energy lostleaves the resistor in the form of heat.The number of joules of electrical energy lost and heat dissipated by the resistor is(amperes of current through the resistor)2 x (ohms of resistance) x (seconds of time it continues)If you work with resistors often, or see several of them inside an old radio, you noticethat there are physically big ones and physically small ones. The size of the resistorisn't related to the number of ohms of resistance it has. The physical size is relatedto how fast it can dissipate energy (heat) without melting or burning up. A biggerresistor has more air around it, so it can get rid of heat faster.


Make sure you have only about 8 volts going to it not a full 12. There is a resistor wire that should cut the voltage.


A circuit does need resistance but not necessarily a resistor. without any resistance a circuit will be considered a "short circuit" and you power source will most likely overheat. Resistance can be created in millions of different ways. This could be something such as an or any other light source but also a module such as a capacitor resistor or diode. To get to you're question more directly a circuit needs resistance to keep from shorting out. A specific module(such as an LED) would need a resistor to lower the voltage so to a point where the module can accept the power without burning out.


It means that the resistor will safely dissipate the heat involved in transporting that much power through, without burning up/out. If you exceed that rating, the resistor will become too hot for its own good.Power is always linked with Voltage and Current, and Current is linked with Voltage and Resistance of the resistor. You will do well to remember the tandem of laws:Power [Watts] = Potential [Volts] * Current [Amperes]andCurrent [Amperes] = Potential [Volts] / Resistance [Ohms]For example, if you have a 100ohm resistor rated at 0.25W, then to satisfy that requirement, a voltage of no more than 5V can be applied to it, because 5V / 100ohm = 0.05A, and 0.05A * 5V = 0.25W.


You are looking at the wrong fuse. The fuse you wish to check is the blower fuse.If the fuse is ok, these cars have a problem with the wire going to the resistor block burning up. The main power going into the resistor is probably burned off of the connector. The resistor sits inside the vent system under the passengers side dash.


That's to avoid the diode from burning out. When it is forward biased, the resistance is extremely low; so even a small voltage can produce a large current, and that can quickly damage it.


First dissable the air bag system, open the glove compartment, squeeze the side in to release the glove box stops and lower glove box. You will see the Blower Motor Resistor directly behing the glove box. There will be two pig tails (one vehicle harness, one resistor), remove pig tails, remove two screws to free resistor. Replace resistor, reverse removal procedure. Done. Not sure, but the local Dodge dealer just quoted me a $945 price to do the replacement. I was told the dash and part of the AC system must come out to get to two bolts. I had the resistor replaced 3/07 because the motor would only work on high and it just now started to only work on high again, 11/07. Dealer said the motor was pulling more amps then it should and this was burning out the resistor. Resistor was garenteed for 12 mnts but since I opted to NOT replace the fan motor they said they could not garentee the resistor again.
