Well, I worked on the air level system last weekend. I started by using Alldata to trace the power circuits, and after climbing around in the trunk with my flashlite, dvm, tablet and a jumper wire, and answering a bunch of YES questions, it finally led me to the power connector under the car, just below the compressor! When I read that, I slapped myself and said "Why ddnt I just test the compressor itself, 1st, to see if it's even working!" I did, and it isnt. I took the whole thing out. 3 bolts to separate it from its mount then take mount out, then you have to take the dryer off the pump, or it wont come out. Took the crankcase cover off and looked inside. The crankpin had broken off the motor shaft rotating gizmo. Motor froze up, but piston looked ok. Tried to make 1 of of 2, by putting that "good" piston in the compressor that had quit pumping, and that I had taken out of my old Eldorado, years ago, but couldnt get it apart. The electric motor shaft goes through the crankcase wall and is pressed into the rotating gizmo. I had already ordered the airline kit that Basscat suggested. Should be here anyday. I thought about rigging a Schrader valve to the little end of the dryer and plugging it back in to the airlines! One way or the other I'm gonna get some air in it, to save the new shocks, until I can get a new compressor ordered. The system works, because I plugged the worn out pump in and with the level control lever, I could make it turn on and off! Thanks guys!
