I have a 1993 E300 4Matic.(no this is not a 4Matic question my works fine)

. The question I have is on the climate control system. My fan went dead and at the same time my a/c compresser is not kicking on or off with the dash controll buttons. When the different buttons are pushed you can hear the different flaps opening by way of the vacuum system, but I get nothing. The question is does the death of the fan motor also kill the a/c compresser from kicking on? Is there a way to test the a/c compresser or test the fan? Or does the dash control unit need to be operational before any thing will work and how do you check it for your problems. I have checked all the fuses,and thay are fine.

Thanks, IT'S GETTING HOT
