Question Blower Motor Resistor Harness MELTED

Hello my fan setting only worked on high so I opened up the blower motor resister to find out that it was melted in to the connector and I am wondering how would i fix the connector so that i would be able to replace the resistor itself? here are some pictures for more details

Anyone know where i can buy the harness/connector for my 97 wrangler?
Or is it called a pigtail?
If you cannot see the picture try right clicking and then open it up :]












So any help?

I ended up cutting the connector off on my '97 after it melted, I simply spliced the wires together. A possible cause for the wiring and connector to have gotten hot enough to melt is a bad fan motor. When the HVAC fan motor goes bad, it often starts drawing much more current than the wiring and connector was designed for.

I have a good resistor pack I no longer need since that Jeep was stolen and my newer TJ uses a different type of resistor pack, PM me with a reasonable offer if you want it.

I don't think i need the resistor pack because i just bought this DORMAN 973-021 A/C Blower Motor Switch/Resistor | eBay

Now i just need to get the female resistor connector. I think... this: IMAG0559 | Flickr - Photo Sharing! because my old one(as you can see is melted) but i just don't know where i could buy it?...

I just found this product 2002-2006 Jeep Wrangler HVAC Blower Motor Resistor Connector - 2973305 Replacement - Climate Control 02-06 Wrangler HVAC Blower Motor Resistor Connector - PartsGeek.com Do you think it could fit my new blower motor resistor even though it is labeled for 2002 - 2006 (I have a 97 tj wrangler btw)

Won't work, that is for the newer style resistor pack that uses a different connector.

Do you think this would work? Dorman Products - 973-305

The product description said "2001-97 Jeep Cherokee, Wrangler..."

That looks like the right model. Nice find!

Don't forget your blower motor might be the reason it all melted in the first place.

HeyItsWinner or anyone else- Did that wiring harness work (Dorman 973-305)? The description says it will work (2001-97), but when i click on the "check your fit" link the site says its not compatible with a 97 jeep wranger 4.0. Just curious as I'm having the exact same problem...melted connector.

Thanks in advance.

Look at part 973-416, same exact thing but it's a kit with the resistor and pigtail. When doing the "check your fit" it says it fits. I'd say it's an error in the system, 973-305 should work.

So did either of you guys buy that Dorman part and did it work? Found the same problem... replacing the blower motor tonight, but would like to get the right connector too.

I bought these and stuck them all over the back of switch and resistor and connectors. Figure if they are going to make heat take it away like a radiator. Have had no further melting since. My connectors are a little melted from before and I have a new switch and resistor same fan. Been around 2 years. I reviewed them can look at the date.

Thanks man. Works well. Noticed they are no longer available on amazon. They are copper which is the best heatsink aluminum is good and cheaper but copper is best. I'm sure similar products are available. Maybe even on amazon. Might find identical on eBay. Was like peel and sticking little copper porcupines all over my stuff. and female blade connecters can be crimped on your wires for the resistor if the connector is shot. Just remember (better yet diagram) which goes where as they will all be separate.
