I have replaced my resister pack about a year ago. Not only was the pack bad but the wiring harness that plugged into was all meted. I bought a factory replacement and installed it. Now I am having the same isssue. Anyone know what is causing the harness to overheat and break down?

Problem solved for me, I've had the same problem since last winter and after two motors and three resistors I got tired of paying and decided to investigate the issue, I've seen people say too much power is being drawn, so I tested the motor draw and it's perfect. then looked into the plug itself what I found out there is the plug is making minimal contact at best on the first two prongs, so I cut the plastic back off the resistor exposing the prongs and soldered each wire onto its prong and ran it for an hour and the wires are as cold as ice, it used to heat up immediately, problem solved, so if you can solder your good to go if not, learn it's beneficial!!!!!!!
Now in the 2004 Durango the resistor was changed because of the burn out fault on previous models.So,my second one is in,if it burns out again I will put in the new resistor from a 2004 and up model.What a pain.
So over time, water was leaking back into air system, draining down into lowest point (yes, the blower motor casing) and causing blower motor to burn out the resistors and melt the resistor plug (but the blower kept running - poorly). It was insidious, because it starts out slow and you figure there is something wrong with resistor, resistor connector (which melted) or the blower motor's old, or they-don't-make-these-blower-motors-like-they-used to. Replace everything or directly soldered wires to resistor to no avail. It happens again (until water leak was so great I couldn't miss it).
Like I said, there are multiple videos and forums discussing this A/C condensate leak back into the vehicle and how to repair that. I managed it by turning wheel left, jacking up truck and reaching in to pull off drain shield and then putty up cracked drain hose and all around the hose penetration.
My problem solved - finally. This may be your issue. Especially if you didn't have this problem all those wonderful first years with the truck. Good luck.

I'm going to try that, My 01 Dakota is always soaked on passenger side.
