Question about Mercury Grand Marquis

1 Answer

I just got a 1993 Mercury Grand Marquis SRS from a family whose only owner was an elderly lady, and it sat alot. I had a variety of issues: 1) I try to put the key in and it won't go, when I look to the side it looks like the key slot doesn't line up and when I do get the key in the ignition turns and the key doesn't. 2) It ran fine when going slow speeds then when I stopped and started again, when I got up to 45-65 it shook like the dickens and scared the crap out of me it was so rough. 3) The air bag light keeps on blinking. Before I got it, the people before me changed the battery. I can't tell what error code its blinking to know whats up. 4) Right rear window went down fine, but when I tried to get it to go up it wouldn't go. The window seems to not be in line with the motor or something? I could smell it when I tried to get it going, and had to push the window up as I saw it not quite in line like the other windows. Other windows went up & down fine.

SOURCE: 1999 Merc Gr Marquis: Air Suspension Warn Light / compressor

Try calling several Autozone stores and see if the have a scanner for the air suspension.

There are height adjustment sensors under the car and it may be that a sensor got smashed or failed. I remember reading this tech stuff about 20 years ago for a 1988 LSC. As long as the air is not leaking and the compressor runs its a plus.

I always recommend going to a Salvage yard and asking about the parts and asking if I can look at where the parts go. That way you are not tearing up your car trying to do something you don't have tools for.

SOURCE: How to install a new power window motor in my 1993

Remove all screws to door panel. Remove the lock and window controls. Then take large flat-tip screwdriver and gently pry directly next to plastic studs holding panel on to door. Lift door panel off. Remove plastic out of the way. You will now have access to window motor. You may have to solder off old wiring. Or if you have enough to cut, would be good

Have your alternator checked. Most auto supply places do this at no charge. Multiple dashboard warning lights usually indicate alternator problems.

1994 mercury airbag code 34

You can't disable the system to turn the light off. The system is disabled when the light is on.
Code 34 is for the driver side bag circuit, which could be several different issues. I never recommend car owners working on SRS but you can buy a shop manual and give it a try if you like.

How do I reset the door lock code on a 93 Mercury Grand Marquis if I don't know the current code. I bought the car from a family and the owner had passed away and they don't know the current code.

There is a master default code that will always work no matter how the personal codes are set. Codes are 5 digits and should be on a card hopefully in the owner's manual packet. If you can't find the card, any Ford dealer can retrieve the master code for you. Even if you knew the previous owner's code, you'll need the master code in order to program a personal code of your own.

Good luck.
