my 02 ram's ac is all jacked up as well, the switch only works on the highest speed and it only works on the drivers side, and while your moving, the ac condenser fan doesn't work, and i hear the switch is called the blower motor resister switch
Dammit.. I have an 02 dodge and the ac fan won't run unless it's wide open. Took it on a trip and it quit blowing cold. I let it rest a while and it came back ok. Looks like I'm fricked. Did you have anybody look at yours and if so, how much to fix it?
