Fuse #20 located in fuse panel located in the engine compartment near the brake fluid resevoir blows as soon as I start A/C in my 1997 S420. Some further information and a few problems that may or may not be related on my 1997 S420 are as follows:

1. Fuse #20 blows every time I start A/C of the car. The things listed against that fuse are Control Unit, A/C Compressor, Automatic climate control. I turned off the A/C and then replaced fuse #20 and re-start the car not working after going to workshop and reprogram the car it started and again turning on A/C the fuse blows and the car not started till reprogram and also the center lock of remote is not working after this happen but it working from button inside the car.
