Had the R12 topped off at an a/c place that I respect and the tech said that my aux fan wasn't working. He put a jumper to it and it operated OK. It is apparently controlled by an internal switch at the filter/drier. Tech says that most likely the system would have to be open to fix the switch.

Does that seem right? Would I be OK just jumping it with a wire in the summer and leaving it off in the winter?

Don't really want to change filter/driers and goto the extra expense unless it't going to cause me problems during my 15 minute commute.

Thanks.
