1999 Cadillac Deville air ride

I had the same problem in my 98 Deville - My son-in-law changed the 2 small O-Rings at the pump by the rear axle - Never had a problem again. Hope this helps.

hi, when driving with alot of weight in car (5 pass + lugage) car loses air in suspension and air pump won't go on to refill air struts. so i bring car to stop & restart car, wait a few seconds and air ride pump gos on car levels and start driving. 10 minutes later same thing. i figure theres a leak when lots of weight but should the air pump go on to compensate. also air does not leak out when not alot of weight or sitting over night.[/quote:b83ad9be48]

sounds like a leak with a load, you can add some ac die into the air line system, and ck it with a black lite, to find the prob

thanx everybody. after the holidays i am going to fix the caddy. i will post the results (good or bad). talk to you soon in the new year.
