Mercury Grand Marquis

On the RH 1998 Grand Marquis Door, 5 screws exist that require removal

1) Pop the door handle screw covers. Remove both screws...on the right is a hook be careful removing the door handle

2) Below the door handle is another screw around them middle of the door. Remove this one.

3) On the right side of the door panel is a screw on the side. Remove this screw

4) At the bottom middle, remove the screw.

5) Unsnap the switch panel for the lock unlock/window rolldown switches. Flip this over. Remove both screws and unhook the wire interface.

6) At this point from the bottom, gently and slowly pull the door panel up about 1/2 inch to 1 inch. Then, pull the panel away from the door.

7) The door panel will still have the wires for the window motor hooked up. Unplug this interface.

8) Now the door panel can be removed and set aside...keep those loose screws handy...place them in a bowl or container...remember which screw matches which hole ...at least two different sizes...long and medium.

9) Remove the three outer speaker bolts...you can leave the speaker cover on. Set the bolts aside.

10 ) reach behind the left part of the speaker frame. This wire should tie into the mirror. You may want to unplug this from the door frame. Once you do, unplug the mirror interaface.

11) At the top left, pull out the plastic plug covering the mirror area. Then take off the plastic part...be careful.

12) Three nuts secure the mirror. Unfasten them..think you need a 7/16 or 9/16 ratchet. Left to loosen.

13) Remove the old mirror.

14) Install the new mirror...and tighten those three nuts to the right.

15) Plug the wiring back in and test the mirror.

16) Continue by reversing the process from step 10 to step 8

17) Step 6 ...achor off of the door lock/unlock stick. Be Gentle...and repeat the step 5-1 in reverse order. Enjoy!

Oh, dude, the transmission dipstick on a Mercury Grand Marquis is located towards the back of the engine bay. It's usually a bright color, like yellow or red, because, you know, it wants to stand out in the crowd of car parts. Just look for a long, thin stick that's like, "Hey, I'm the transmission dipstick, come check me out!"

Several factors could prevent a 1992 Grand Marquis from starting after replacing the starter, battery, and solenoid:

Faulty Ignition Switch: If the ignition switch isn't sending the proper signal to engage the starter.

Bad Starter Relay: A malfunctioning starter relay could prevent the starter from receiving power.

Corroded Battery Cables: Poor connections due to corroded or loose battery cables.

Ignition System Issues: Problems with the ignition coil, distributor, or spark plugs.

Security System Activation: If equipped, the vehicle's security system might be preventing the engine from starting.

Ensure all connections are secure and consider checking these potential issues to diagnose the problem.

The starter on a 1992 Grand Marquis is located on the passenger side of the engine, near the bottom. It is mounted to the engine block and can be accessed from underneath the vehicle.

Since there is no real atmosphere, just a low, thin collection of ionized gases, there is no real "weather". The surface temperature, however is extremely hot when you're on the sunny side, and extremely cold when you're on the shady side.

Mercury has two characteristics that make its surface temperature interesting. One is a highly elliptical orbit that takes the planet from 46 million km at perihelion to 70 million km at aphelion. That means the solar intensity varies from 4 times the intensity at Earth to over 10 times. The other aspect is that it rotates only about one and a half times per Mercury year. This makes a solar day on Mercury (sunrise to sunrise) apparently 156 Earth days long. A point that gets hammered by the maximum solar intensity will be in the frigid dark 88 Earth days later. The day side temperature can reach 700 Kelvins (about 430°C, or about 800° F.) Curiously, Venus is hotter at the surface than Mercury, even though it is farther from the Sun. The dense atmosphere of Venus holds in what little solar radiation makes it through the clouds, while Mercury efficiently radiates back to space. On the dark side, Mercury can be as low as 90 K (-183°C).

I suspect that your Control Unit itself has gone bad. That's what happened to me. A new control unit will cost between $400 and $500. I got one from a Junk Dealer for $100. It's been working for 3 years now. The control is real easy to change out. Hope this helps.

The hoot sound you are hearing could be due to a vacuum leak in the air intake system or a fault in the idle air control valve. Have a mechanic inspect these components to determine the exact cause and make any necessary repairs.

loosen belt

remove wiring plugs

remove part that has the metal tube going to it. It will leak freon if your system is full

there are 4 bolts on the front of the compressor connecting it to the engine, remove them.

lift compressor out.

this is from the top of my head, so sorry if it isn't exact, but will give you an idea. takes about an hour to change for the average person with proper tools.

To reset the keyless entry code, you need to first enter the factory programmed code. Once entered, press the '1-2' button within five seconds of entering the last digit. You can then reset the code to your own. You will need to be extremely quick.

For a 1988 Mercury Marquis remove bottom shroud from steering column (5 Philips head screws). There is a wire running from the ignition switch to the left side of the steering column; detach it from the coupler (This can be done without a tool). Turn key to ON position until the panel lights come on. There is a small pin near the bottom of the key lock; push it in and pull the ignition switch out (don't panic if the wire seems to be stuck; it will come out).

To replace, turn new ignition switch to same position. Push pin on the ignition switch in while sliding it back into the steering column. Reconnect wire and then replace shroud.

To replace the door hinge pins on a 1997 Jimmy you will need to open the door up. Place two jack stands on the front and back of the door's length at the bottom portion of the door for support. Remove the damaged hinge pin with the proper socket. Place the new hinge pin in place and secure it.

Lift the hoods, find the lid to the power steering reservoir and remove the lid. Attached to the lid is the dipstick to the power steering fluid, read the level and decide if more needs to be added.

If you are asking for a 1996 or newer model year, it is located just below the dash on the driver's side above the OBDII port. It is not hard to access. Drop the lower dash panel for light access and uncouple the harness clips. Slip it back and replace with the new one.

Buy a can of refrigerant and a separate feeder hose. This will help recharge in future years--instead of paying a garage $90 a year or more to recharge or $300 or so to find and fix a slow leak in the system... You can pay $25 for the can of refrigerant and hose and about $10 a year for the can. On the passenger side of the engine there is a quick-connect coupling for the coolant. This is the low pressure side of the system, and it is where the can of coolant goes into the system (through the hose, which also has a quick-coupler). In the front of the engine, near the radiator, there is another coupling, but this is to the high-pressure end of the system. The hose coupling will most likely not fit this, but if it does, DO NOT ATTEMPT TO ADD COOLANT TO THIS SIDE OF THE SYSTEM.

Jack up the passengers side of the car, get a 1 1/16" wrench break loose the fitting to the manifold, hold a 24 mm wrench on the fitting to the manifold, loosen the flare nut on the tube. Then using a 10 mm socket, about 2 inches long, loosen the two nuts under the EGR valve, then take the both out, remove the vacuum hose to the top of the EGR valve, and the sensing line from the small tube. then completely remove the flare nut from the orifice fitting on the manifold. BE CAREFUL with the tube, do not bend it or break it, you may find PB blaster useful the night before on a cold engine loosen these fittings. Once the EGR valve is out, remove the orifice out of the manifold, remove the tube from the EGR valve, again be careful, mark the tube to EGR position before pulling this off, because the top fitting to EGR needs tightened before you put it back in, it will make the lower fitting difficult if you do not line it up right, dry fitting from under the car is helpful, mark it, and then tighten the top. Clean out the tube, be careful not to bend the little tube, either inside or outside the larger tube, it sticks out inside. Clean the orifice, clean the manifold face carefully not to score it, check for blockage there too. Apply antisieze to the orifice, put it back in the manifold, then apply antisieze to the bolts for the egr valve, and the flare nuts both ends. Apply some silicon to the egr valve face, just enough to hold the gasket in place, put the new gasket on, start the bolts two turns in the gasket, it will hold them in place, then start them in the manifold, then start the lower flare fitting to orifice, tighten the top bolts, and then the flare nut, connect the vacuum line, connect the sensing line. I just recently did this process, it works, if have other EGR issues, the valve is the easiest.

The 1990 grand marquis 5.0 has what they call an "AIC" motor. It's located on front left side of throttlebody. It has a PINCLE valve inside that gets dirty. Take it apart and clean with throttle body cleaner and disconnect the battery, wait 10 min, connect battery, start it up and let it idle for 5mins , then take it out for a brisk ride to let the CPU relearn.

If it's Like my 2000 (I'm sure it is) remove the wheel and tire, remove the brake drum, (it might be necessary to use the threaded holes in the drum to run bolts in and pull the drum off, the bolts needed are METRIC). On the rear of the axle housing by the backing plate is the rear wheel antilock sensor, held in by one bolt with a 12mm head. Remove this sensor. After the sensor is removed there are four 12mm head nuts on the back of the backing plate, remove these. I had to get a little physical with a deadblow hammer to get the backing plate to break loose, the axle shaft, outer bearing, and backing plate come off as one assembly, the outer bearing is press fit into the axle housing so it will require driving it back into the housing on re assembly. Hope this helps.

# Close all the vehicle doors. # Insert the ignition key into the ignition lock cylinder - do not turn ignition switch. # Press and hold the DOOR unlock switch (This is the switch on the door, NOT the remote). # While holding the DOOR lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF ON, OFF. (3 TIMES) # Release the DOOR unlock switch. The doors will lock and unlock one time to confirm the program mode is actuated. # Simultaneously press and hold the LOCK button and the UNLOCK button on one keyless remote for approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter. # Repeat the previous step to program up to four transmitters. Reprogram any existing remotes at this time as they have been erased. # Turn the ignition switch to the ON (one more click forward) position in order to exit the keyless entry transmitter mode. # Operate the transmitter functions in order to verify correct system operation.

Pop the trunk, and there should be a sticker on the drivers side support arm that hold the truck lid with the number code. If this is the case, and you're styling now, note that right after you enter that number, and the door unlocks enter "3" to unlock the passenger door, and "5" to pop the trunk. Keyless entry with remote key fab? Have it, or not. Get in the car. Lock the doors. Cycle the ignition key on and off, one right after the other about eight to ten times. If the door unlocks by its self this car is equipt with such a keyless entry. Ford dealer can get you a new key fab for cost of labor to discover needed code for this must have. c-ya grade a da mopar man! Codes are usually on a white sticker inside of the trunk - it's 5-digit number. If it's not there - it could be written inside of the Owners Manual or on a sticker inside the Glove Compartment. If it's not there - I believe the Dealers can get it. Hope this helps. The code can also be found stamped on a label on the device itself. Mounted to inside of driver door... another black box with a lot of wires coming in/out of it. -motoman22

Believe it or not, the easiest way is: 1. Remove the plug wire by pulling it off carefully, grasp it close to the end. You can also buy a plug wire remover which is available at any parts store. 2. Using a SPARK PLUG wrench (available at any parts store) - remove the old plug. 3. Insert the new plug. 4. Tighten, but not TOO tight. 5. Push the plug wire back on. 6. Repeat 1-5 for the other 7 plugs. You might find it easier to access some of the plugs via the holes above the tire wells. From the side of the vehicle, you'll see a hole near the top of the tire well. If you change the plugs, it's best to replace the wires also. NOTE: The wires and plugs on Grand Marquis are rated for 100,000 miles or more with proper maintenance. NOTE 2: Unless you area good mechanic, changing the plugs can cause you more heartache than the price of having a professional do it for you. With all the Computerized stuff on 2000 model year and later automobiles, it's best to pay a price for a complete tune-up. Good Luck -tj-

There is an electric motor that drives a geared pulley which is attached to a sliding bracket attached to the window. Most of the time the cable jumps off due to dry or binding window/channel. There are rubber spacers in the gear attached to the motor that deteriate in the heat and crumble. You can buy a new gear kit and replace it.
