The relay which turns the airmatic suspension pump on may fail causing the pump to run continuously. This can result in failure of the pump motor or a dead battery as the pump motor will continue to run after the car is turned off. Also, Worn airmatic pump mount bushings can causes noises in the front axle while driving on bumpy roads or a buzzing noise while the pump is running.

I have not had this problem fixed. I was wondering if anyone out there had the same problem. I can't get the trunk to open using the key or the remote.

CD changers, command units, voice control units, PSE units, and Tele Aid units are prone to failure, especially in early models.

The only part I have replaced is a heater control valve in the cowl area, $175.00. no big deal. The car is adult driven and yes I did buy this car new. Going on a trip this summer and I am planning on replaci...

Not what it should be. Over rated. Too costly for every little service. Floor mats are not good....they should be attached to the floor so they do not move. The AC is not very strong ( I live in Flporida) takes too long to cool the cab. I do not like the windshield wipers, with it auto wipe on rainy days. There are a lot more problems........... for the price ......it sucks.
