Lincoln/Mercury Repair: Air suspension, Coil spring conversion, hard fault


Question
QUESTION: I have a 99 lincoln towncar cartier edition.I had gotten
into an accident and started taking the car apart.I would
hear the compressor come on when I would turn on the
ignition but after I removed the radiator,fan and took off
the whole front end and both fenders.After doing so I
would turn the ignition key to on and the compressor
wont turn on anymore,so basically my car is a lowrider
now.what can be wrong?

ANSWER: Rafael,
  So, are you saying that both fenders and assorted things are "still" removed from the vehicle. If so, I don't know as I would worry about it right now. Theres a really good chance you unhooked a ground or something for the compressor. Keep in mind that if the system tries to make an adjustment, it'll assume the compressor is coming on, then open the rear solenoids. If the compressor really isn't coming on for some reason, there will be more air pressure in the air springs than the compressor is putting out.....so the air will actually vent out and the car will slam.

Again, I would really worry about it until everything is put back together. If you do have a problem then, just give me a shout and we'll get you going again. Good luck.

If everything IS put back together and you still have a problem, check the fuse under the hood closest to the pass. side fender.

QUESTION: I  grounded all the wires to the chassis with some
success.I turn the key to on and it turns on for a few
seconds then shuts off.The thing is that the rear will not lift
up.I don't want to replace the airbags for not letting air in
them.What can be causing the car not to lift up from the
rear and what can be turning the compressor off after a
few seconds

Answer
Rafael,
  Sorry, extremely busy weekend. No, I definitely wouldn't say to replace the air bags....as they are doing what they're told to do. Not knowing for sure, I'm assuming the "check suspension" message is coming on after a few seconds?

With that being said, keep in mind that when the car is first turned on, the module(brain) looks at everything real quick. If it see's something it can't deal with(something out of range), it'll shut down the system, turn on the message and not make ANY adjustments.

What your experiencing is what is called a hard fault. Really the only thing you can do right now is to get the code(s) pulled to know where to start. Once you have a code(s), then you can start the pinpoint tests to track down the problem. The problem could be anything electrical at this point and throwing parts at the car WILL get very expensive real quick.

If your looking for an inexpensive way out, nothing is cheaper than a coil spring conversion kit. You can get one for a tad more than what the dealer will charge to pull the codes! http://www.americanairsuspension.com/cart/products.php?cat=30
