Chevrolet Trailblazer SS Rear Suspension Low Due to Failed Air Compressor

(19 reports)

On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.

air bags deflate overnight from time to time. Pump up right away and stay inflated. Annoying problem on a great truck! -
blown fuse , not -
Lower down by its self. When not running -
Noticed when i'm in a bumpy area the the truck hits it hard. There seem to be no bounce, the rear end dart quickly to one side which makes me feel like I'm gonna have an accident. The springs are very squeaky. My cousin took a look underneath the truck and he said the "airbags" were not inflated. I have not come to a solution for the problem because I'm getting my other vehicle repaired therefore I need one to drive. -
Rear air bags leak down over night while truck is parked. -
Only one side of my air bags will fill up n I don't know what I need to do to fix it or if it can be fixed i just bought two new air bags. Because I could hear my compressor running so I thought it was ok but I guess I'm goin to have to buy a compressor now. This is some bullshit!!! -
Air compressor cuts on rises up all the way sometimes and sometimes it rises up just barely ...what is causes this -
This is the second time this has happened. The first time, the fix was easy. The fuse needed to be changed. This time I don't have my owner's manual and I can't remember which.fuse to change. -
AIR BAGS DOES NOT INFLATE CAUSING THE SUV TO SIT LOW. SOMETIMES WHEN I HIT A BUMP ON THE ROAD CAUSES THE VEHICLE TO DO A QUICK SHIFT, WHICH I FEEL IS VERY DANGEROUS. DOES'T DRIVE THE VEHICLE THAT MUCH BECAUSE OF THIS PROBLEM. -
I had the same problem with my TBSS several years ago at around 60,000 miles. First problem was nightly deflating. Simple solution was to tighten all the air line fittings between the compressor and the bags. Second was the compressor gave out. I drove for a long time without the compressor (solving the air line leaks helped)then every once in a while, especially if the outside temperature dropped, I would "air up" the bags with an air hose. I finally bit the bullet and replaced the compressor and it's been fine for 36000 or so. One tip I'll suggest is not to use the compressor for long duration, like to fill a flat tire. I believe this is what killed mine. Good luck -
