I have lost powe to my H/AC system. Nothing will come on. Is there a fuse under the hood or is there a connection that may have come loose. Any help will be greatly appreciated

 

This happend to me in my 1988 b2200, look in the fuse box right by the steering wheel and for me i just pulled out the fan fuse and put it back in, it then worked fine. Not sure if this will help in this case, but i spose worth a try.

 

it could also be your resitor under the glove box on the fan
