I'm told it will cost approximately $700 to get shocks repaired. However, a friend tells me this is totally wrong and it will cost $700 for some type of hydraulic air lift? Please help. I'm told it will cost approximately $700 to get shocks repaired.

    On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sag.and I found a compressor here www.parts.com for $368.00 plus shipping but make sure this part is needed before ordering

    I had this happen. The problem was broken power leads that run UNDER the car. Might have been eaten by mice. The compressor is supposedly very reliable, and few are ever replaced.

    I actually had the same problem. Its not the shocks. First, check the air suspension fuse under the hood. I'm guessing it needs to be replaced. If the fuse is good that means you have a leak in the pressurized air bags which keep the car suspended or the compressor itself is not functioning. The air compressor is supposed to fill the air bags up when the leveling system detects an imbalance which raises the rear of the car. Some have opted to replace the air ride with traditional springs.

    We have been battling with this issue for many weeks. We checked the fuse, replaced it - but it kept blowing. The rear end of the car was riding on the tires so we put coil springs in it just to lift it up off the tires and now we are having problems with the AWD locking. We are not sure what to try next? Is there anyway to blow up the air bags in the suspension manually and leave them up? I am wondering if having the rear sag is causing more issues with the AWD?

    that happened to us too.......it was the suspension motor that needed replaced.......it had a slow leak, and as long as the car was on the compressor would pump it up, but when the car sat over night, it would leak and in the morning the back end of my buick would be very low to the ground
