Need help with wiring under dash to blower motor resistor

I just replace my blower motor resistor because my ac was only working on high. The funny thing is it would go out all the way and how I would fix this is by pounding on the part just beneath the glove box. Worked every time and got the ac going strong! but i thought it was just the blower motor resistor but now i am led to believe that its the wiring behind where i hit because now i still have the same symptoms except i can now use different fan speed settings when it is blowing. Anyone know how to get to this wiring?

Sounds like you need to blower motor wiring kit. You can find it by searching the internet, or go buy it from the dealer. Since you already bought a resistor, be careful not to buy the resistor/wiring kit.

Here is one from eBay: http://www.ebay.com/itm/1999-2004-Je...443b7f&vxp=mtr

And one from JustforJeeps.com: http://www.justforjeeps.com/wjblmocowire.html

1AAuto has it also: http://www.1aauto.com/1A/blower-moto...BR00003/673663

When I got mine, I made sure to solder the wires, but if you use heat shrink, remember to put it on before you solder the wires together.
Good luck.

YZ212-Thanks, I knew I used the Chrysler number when I bought mine from the dealer. That's probably where I found it.
JAKERS13- All you have to do is unplug the melted connector, cut the wires, and splice in the new ones. I think it comes with instructions, too. You have to be somewhat a contortionist to do it, as you pretty much have to lay on the passenger side floor while cutting, splicing, and soldering. I got so tired and hot that I almost gave up on soldering, but I knew that the problem would show up inside burned electrical tape or heat-shrink. That blower motor pulls a lot of amps. If you just wrap the wires together, you are going to start getting some resistance as the wires age, and with amps and resistance comes heat. That's why I soldered mine.
