Question about 2001 Cadillac Eldorado
This is a pretty common problem for cadillacs, moct cadillacs have an excessive moisture problem. Excessive moisture in an air suspension system is mainly hard on compressors. One of the first things to go on a compressor is the vent solenoid. The reason for this is that whenever the vehicle vents(lowers), moisture is blown through the compressor, through the head of the compressor, through the vent solenoid, and then to the atmosphere. In a nutshell, the compressor is taking a bath everytime the car vents. The vent solenoid is basically just a little metal piston that goes up and down with a coil wrapped around it. When its subjected to moisture frequently, rust and corrosion will soon begin and get worse as time goes on. When the rust & corrosion gets bad enough, the coil won't be strong enough to move the metal piston any longer and becomes inoperative either in the open or closed position. If it freezes up in the closed position, the vehicle cannot vent the air in the air springs like the module wants it to. The result is a higher than normal rear height and a usually check suspension light on. What is commonly done, is just replace the compressor. This will get the vehicle operating normally....temporarily. Because nothing was ever done about the moisture, it will soon overwhelm the new dryer and damage the replacement compressor. To cure the root cause of the problem, you must remove the moisture from the system or protect the compressor from the moisture. The Dealership says to replace both air springs, replace the compressor/dryer assembly and replace all the lines in the system to the tune of about $1500.00. There are some alternatives though. You can buy an after market conversion kit for about a quarter of the cost of O.E air ride parts. To learn more PLEASE GO HERE
