Vannin' Home Forums Thread Like Summary - Hopefully the last A/C question.

94 gmc vandura keeps blowing the blower motor fuse. I've replaced the relay and resistor. After doing that it worked for maybe a week. Being that it's not a daily driver it only gets used every other day or so.

My question is is there another switch or something of the sort that is common to go out in these vans that I'm missing? Or is it best to just start chasing wires?

The fan switch needs to be checked first. They can overheat and short between speeds. If nothing else you should rule it out before chasing wires.
