Bad pump or a leak. Pull the lines fro the rear air shocks, Fell for pressure build up in the line. Find the pump, and check pressure there also. No pressure at the pump, it's bad. Pressure at the pump, but not at the shocks, bad line. Pressure at the shock line, bad shocks.

I have a 2002 Bravada w/air suspension. When the compressor is loud it is bad. I bought a new one for less than $300 off the net but after 6 months it is not inflating the rear even though it runs briefly after start-up. It is most likely the compressor check valve. The Compressor Service Kit costs about $25 at the dealership. My rear air springs went bad (right side first) with cracked rubber and leaking. The right side was always lower when it would inflate and would leak until the whole rear was down. New air springs are about $85 w/o shipping @ GMPartsDirect.com. Also, the sensor can go bad but my buddy who works on Bravada/Envoy said this is usually NOT the problem. Compressors go bad after a few years and the air spring rubber deteriorates causing leakage. If the air springs leak, the compressor runs alot more and wears out faster. I'm not a certified mechanic, but have replaced the compressor myself and it took about 2 hours. As for the Compressor Service Kit instructions- you can search "Bravada Letting You Down?" on the net and a tech gives full instructions on how to service the compressor. He states that the compressor check valve sticks and it will not build pressure to inflate the rear of the vehicle.

What has probably happened is you got a hole or cracks in your airbag. Dealerships and mechanics typically diagnoses it as the compressor but that is only to keep you coming back and wasting more money on something that will never truly be fixed. Both the airbag and the compressor are the problem. The compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag will kill the compressor. I would recommend going to strutmasters.com and taking a look at the conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. This is a PERMANENT fix. I added the link below so you can check it out. http://www.strutmasters.com/oldsmobile-suspension-parts-s/85.htm I hope I was of some help Good Luck!!!
Testimonial: "That was exactly the problem...we swapped the bags out for springs!"
SOURCE: rear air suspension is not at level left is higher than the right
I have the exact same problem but my Left side is "Lower" than the right side.... Go Figure, Let's switch Solenoid's... Lol. I haven't seen a fix for this yet... there is 1 ride height sensor bolted to the rear but it's for both sides. the following site seems to be recommended by most Expo owners on all of the ford forums.. Check them out.

That tells me everything is working correctly although you have an air leak in the system somewhere.
