Blower Resister & everything else assoc.

I'm ready to pull my hair out and set this Jeep on fire.

I've replaced the Resistor twice now and then just before my wife had to leave for the airport with the jeep it went out again but this time it burned the wiring harness.

The new harness is here along with a new resistor but the wife has told me that the blower doesn't even work on High anymore. (She's on her way back from the airport.)

What has caused the harness to fry?
What has stopped the blower from working on high? (Did the fan pop a relay?)
How do I stop this from happening again.

I have a new Harness & a New Resistor, both from jeep/chrysler. The first two were from Autozone & Advance Auto and not Chrysler resistors.

If you're burning through multiple resistors (as in they actually test bad), you can be pretty sure it's the blower motor.
If you're melting the harness or connector, you can be really sure it's the blower motor.

When you've done both, just replace the blower motor (and any damaged components), because it ain't gonna be anything else. Motor goes bad in the right way, it eats resistors, melts wiring and connectors, and you end up where you are right now.

Thanks for the reply. I'm not sure why I didn't see such an easy answer googleing through the site. I'll order it tonight and report back the results tomorrow or the following.

same problem here, Replaced the Resistor but the blower only worked on high, I looked at the cable and sure enough, one of the pins is completely melted. How easy is it to replace the blower motor? I Know where it's at just not quite sure if the whole dash needs to come out :'(
