Subject: 85 VW Wolfsburg Camper aircon problem

 Help,
I have a friend who owns a 1985 Wolfsburg Camper, He has a airconditioning
problem. The blower does not work and the aircon clutch does not engage.  We
have been trying to locate the 50 amp aircon fuse but can't find it. Where
it's located? I have a 91 Westy my 50
amp fuse is located in the rear closet behind a panel, his isn't.
Thanks in advance
 Jp
