Rear air suspension

My air suspension on my Envoy. I have been reading through the forum of the topic, and I believe it has to do with my compressor. Usually the pump kicks on and holds a solid red led as it inflates and rises my truck. Now, my bags have been compliantly deflated and the pump switch LED blinks. I am not sure the repetition of the light blinking at the moment, but I can find that out if it is completely necessary. If not if there are only a couple codes it could be producing, what would they be? And is there a way to bypass my compressor and just get my air bags back up again?

Do you
have the same problem?

The only way to by pass the rear is to getnew lines and an air hook up from auto parts store. However before you do that check for leaks using soapy water in a spray bottle as it can be leaking lines/connections or shocks. Check fuse 1 under hood. Then check for broken links or broken off of sensors on rear frame one for each side. Then have it scanned for codes to see what is wrong which a mechanic will need to do.
