Hi. My 2000 S500 is squatting on my garage floor now. Over the last couple of months the compressor would occasionally "run on" after turning the car on or off. Finally, last night the red airmatic light ("STOP, CAR TOO LOW") on the dash stayed on all the way home and it won't go up any more. I checked the relay and it is OK but the 40 A fuse is blown. I'm thinking new pump. It must have shorted to blow that fuse. Question is: Where is the best place to buy the pump. Can you get it rebuilt? Does anyone sell re-furbs? Any input would be greatly appreciated.

Steve
