Land Rover Repair: electrical issues, land rover dealer, vent fan

Question
recent purchase of nas110 1993 model.  recently the vent fan and radio went out at the same time.  as i was driving and had the factory radio on I turned on the vent fan and hit the a/c button. as I was turning on the a/c the radio died and the vent stop blowing air into the cabin. the a/c button no longer lights up. Is there a common fuse for these two accessories. Would you recommend a land rover dealer for these problems on this truck?  Where could I obtain a wiring diagram or wiring book for this Truck?

Thanks in advance for your answer

Answer
I checked the wiring diagram and I do not see that there is a common fuse for the radio and A/C.  The A/C on this vehicle was optional equipment.  Perhaps, it was wired to the wrong fuse.

I would not recommend taking this car to the dealership as they no longer have the wiring diagrams or service information at the dealerships.  Additionally, most of the technicians at the dealerships are not old enough to have been around with these cars were new and have had no training on them.  I would recommend an independent Land Rover specialty shop with experience with this vehicle.

You can get a wiring diagram for your car at Mitchell or Alldata.

Hope this helps.
