One day the fan on my 1990 commanche just stop working. So, I change all the fuses, didn't help. Then I hotwired the fan to check to see if the fan is bad, fan works fine. NOw I am stumped, what could possibly be wrong. One day it was working fine, next day, it didn't work at all. The lights on my dash aren't working either, don't know if that has anything to do with it. Any ideas?
