Air Suspension stuck up
Hello all I have searched the forums and haven't found an answer. I seem to have the opposite problem of everyone else, my air suspension seems to be stuck in the off road position and wont go back down. The info display flashes service air suspension. The truck wont drop even with highway speeds. I have had the bags replaced and had the new compressor installed all under warranty but no more warranty
. I was thinking maybe the ride height sensors, bcm or air compressor module. Any help would be greatly appreciated.

Re: Air Suspension stuck up
I would just let the air out of the bags by pulling the hoses off then restart the truck and see what happens.

Re: Air Suspension stuck up
Check the ride height sensors...are they bent or damaged? Indy

Re: Air Suspension stuck up
Same thing with mine a few months back. It was one of the ride height sensors which was causing the issue. The dealership had a scan tool they plugged into the OBD II which identified the issue and which sensor. Its been fine since repalcement. Thanks....
