'07 Trailblazer SS
I had new Belltech shocks put on all 4 corners and when I picked up the truck, it was sitting on the rear bump stops. It refuses to reinflate the bags. I can manually kick on the compressor using the switch in the back, but nothing I have tried will make the bags inflate. I've pulled fuse #1- no help. I've reset everything by unplugging the battery. I've tried manually adjusting both rear height sensors. I've tried to "trick" the system by partially lifting the rear. I've tried to manually trigger the sensors by lifting the hubs with the wheels off. I have no idea what else to do (other than replace them with springs which I don't want to do since I tow). Any suggestions???
