Air suspension compressor running, but told it's bad by mechanic?????
Has anyone had experience with air suspension compressor problems??? We just took our Mercury Grand Marquis to a local mechanic, and after agreeing to pay 443.00 to replace the two rear air bag units, which he said was the problem, he said our car isn't ready because apparently the compressor is too weak to air up the new air bags. He told us it will be another 379.00 for that part. The air compressor is STILL running, how could it be too weak to air up the new air bags???
I watched him troubleshoot the car the first time, and was a little concerned when he tried to air up the rear air bag units with his shop compressor (by pulling the air line off the car compressor and testing there). He told the other mechanic he was putting in 125 psi, and that apparently there was a line restriction. After jacking around under the car for about another twenty minutes, testing his shop compressor line there under the car, he finally stated he found the problem and it was a leak in the air bag, both bags would need to be replaced. He never said another word about the line restriction. He had said his "lift" was broken when he first started, so he had to use a regular floor jack and stands to raise the car, thus I couldn't see what he was doing under the car, just watch and listen from the side.
Could the compressor sound like it's running strong, but be too weak to air up the bags? To me a compressor is a simple concept, either it runs or it don't...
