Well it seems to only really happen on the rear passenger strut....when I have it switched to high or even with my height controller set to a decent height in the rear it doesn't sink over night or until i have passangers in the back seats. Also if I have it set to a fairly low setting the compressor can't keep up with the air loss. So my question is...any particular reason why the 1 strut doesn't sink with a higher height setting, but it does with a much lower one? Thanks

 

Any one have any idea or know anything that can help hatteroo and me out? I'm having the same exact problem with my 92 ls400 stock air suspension as to what hatteroo said. Please help. When I start the engine the compressor will pump it's way back up at the rear passenger strut to level with all the other wheels and height. It's only one side at the rear passenger strut that goes down. The strut seems to hold air when engine is off and the switch is set on HIGH but when it wants to release the air out it just does it and when it wants to hold the air in it'll hold it for the whole night til next morning or until someone sits in it. Then the air will just release or leak out fast and it'll just go down very fast. Any clue's or help would be great. Thanks.

 

first things first...get a water spray bottle with soapy water.when the car is in the position that it is leaking, start start spraying the bag and watch for bubbles. this will show the leak. if you cant find it on the bag, go to the air lines..


there was one time, and so far just that once, but on a lincoln navigator, I had to replace a left front level switch for a similar problem.

sorry, its all I got.
