I have an 01 Durango and an 04 Dakota, both have the same issue. I've replaced countless resistors, wiring harnesses and blower motors. STILL have the same problem. All of this is wired into the ignition switch. I'm not wanting to replace the ignition. Dodge knows there is a major problem with this issue. It happens on all years and makes of Dodge. Most forums tell you the same thing. Change this, change that. I want to bypass all of it and wire direct. I'm sick of throwing my money out the window and Dodge doing nothing about it. And wouldn't you know, they go out at the most inopportune times. No AC in the heat, and no heat in the winter. Dodge needs to get better "engineers"!!!!
