I have a 1996 Cadillac Deville
I looked up the code and it says:
Electronic Level Control Exhaust Valve Short to Ground/Open.
Does anyone know what to do about fixing that?
You've got the code right. This is a problem with the solenoid that lets air out of the system. Usually it's caused by water that somehow got into the system and rusted or otherwise corroded something away. I just fixed this same problem on my 96 Seville.
You can buy the ELC parts separate from a dealership or from www.gmpartsdirect.com
. There is a pump mechanism that includes the ELC exhaust valve and an air dryer. I think I remember pricing both parts at about $450-500 online, and the dealership wanted over $600. I wound up buying a used one that came from an Olds Aurora for $100. The mounting bracket was different, but easy to change over, and it saved quite a few bux as you can see.
On the 96 Seville, the pump and dryer are mounted above the rear axle. It's a little tricky to find all the bolts that hold it up there, but none of them are hard to remove. You will probably have to remove the clip and air dryer cylinder from the pump assembly before you can remove the whole thing from above the axle. Just be sure you keep the mounting brackets in case you get a used one from a different car. When you remove the brackets, be very careful not to get dust or other contaminants into the crankcase of the new pump. Also be careful not to cut the plastic air lines by pinching them or rubbing them against something sharp or abrasive. If there are already cracks or holes in the air lines, replace them before replacing the pump.
Once you've replaced the pump, also check the ELC fuse and replace if necessary. Clear out the RS0038 code or disconnect the battery for 30 seconds and you should be in business. You will probably notice the pump kick on when you turn the ignition on, and the exhaust valve letting a bit of air out when you turn it off and get out of the car.
Hope that helps! Good luck... :wave:
