2004 Dakota, the blower doesn't work in any switch position. I have replaced the blower resistor, to no avail. The AC still works (as cold air will gently flow through the vents at highway speed w/the AC on). I have checked the underdash fuses, they are OK. Am I missing any simple repair, or is this a switch/control issue. (If so, what is the swich replacement procedure?)
Thanks!

Is the resistor getting juice?

 

Have you been able to find a solution? I joined this forum for this exact problem. All the fuses look good. I tested the power at the switch and it appears to be too low so I need to find the power loss before that point, but I don't know where to trace the wires to. Anyone know?
thanks

 

I had the same issue on my '04 with 31,000 miles,with out a shadow of a doubt it IS the Blower Resistor. I do not know the charge because it was covered under warranty. Hope this helps.

 

I believe the blower resistor is around $10.
As far as tracing wires, go HERE and download the service manual. It like 80-or-so megabytes, but, its a lot of great information. Its a manual for a 2001, but it should apply to other years as well, for the most part.
