First off this is not for a tacoma but rather for my girlfriends explorer. Her car is having a problem with the Vent/Fan/a/c/etc. not working. You can turn the vent fan on full blast and nothing happens, it is just as if you didn't turn the fan on. The wierd thing is that sometimes it turns on after a while of driving with the switch in the on position, but typically it doesn't work at all. Does anybody have anyidea what it might be?
