REAR AIR SUSPENSION

2004 Cadillac Seville • 131,411 miles

I want to find out what could be wrong with the shocks, you can hear the air compressor come on but the shocks are not airing up.

Chances are there is a leak in the air hoses or a shock itself.

The rear air bags devolop leaks. You can spray them down with soapy water turn the key on and shift into reverse. Then sit on the rear bumper. You will hear the pump run when it shuts off. Lay under and look at the shocks if there are leaking youll see bubbles. If no bubbles its a line like j and n said.

Are both rear air bags connected with the same line? Because neither side is airing up.

The compresser is in like the r/r there is the height sensor it has a linkage that snaps on to the rear cross axle bar use a screw driver to pop it off. Then push it up. Then the motor will keep running whyll u spray the shocks and lines down to find the leak. Then just pull it back down and pop it back on. Best done on a lift. But u dont need one to check the shocks. Ty for using 2carpros
