Question about 1993 Mercury Grand Marquis
1990 mercury grand marquis
It sounds to me like your compressor got killed. What probably happened is that the airbag got a hole or tiny crack in it so the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag killed the compressor. I would recommend going to strutmasters.com and taking a look at our conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. I added the link below so you can check it out.
I hope I was of some help

If you don't address it, it will be more serious as in burnt valves, burnt up converter, possibly more engine damage. Get it repaired. Probably needs just a tune up, but needs to be checked to be sure.

The blend door is stuck in cold position. That usually happens because the blend door actuator has failed.
You will need to test and replace the blend door actuator.
To replace the actuator you will need to take apart the dash and remove completely the instrument panel,d isconnect the connector, remove the four screws, remove the temperature blend door actuator and replace it.
The replacement is not a job for beginners, since you have to take apart the dash to access the actuator.

There are eight COPs (coil-on-plugs) to remove. Using a 7mm or 9/32" socket, remove each bolt securing each COP to the intake manifold on top of the engine. Remove all eight COPs, and the spark plugs are underneath. When replacing the spark plugs, use only the proper Ford/Motorcraft plugs, even if they cost twice as much as the aftermarket ones. You will avoid further headaches this way. Hope this helps.
