My towncar the air ride has gone out on it before but all that had to be done was to change the fuse. It went out again and everytime I change the fuse it blows. when I put the new fuse in and I start the car I here a click nosie like the compersor is trying to start but I think the compressor is shorting out. Can you tell me where the compressor is and if there is anything else you can think it might be. thanks
