Can anyone tell me where to locate the Blower motor resistor on a 2004 Dakota. Only working on high. thanks in advance!

 

A flashlight will be helpful. Go to the passenger side and look up under the dash panel. You should be able to find the blower motor easy enough. Go inboard a bit and you will find a bundle of wires going up into the housing. That's it. As I recall, it takes 5/16" (8mm) socket. There's two bolts, and when they're out, the thing just drops into your hands.
I was reading so much about these resistor board failures, I took mine out and attached a heat sink to it.
