I've been having some issues with the airflow, so I crawled under my glove compartment and found the connector with the infamous reversed wires... It's already got the green wires spliced in, so I assume it had the resistor replaced sometime in the past.

I unplugged it and swapped the wires on each side, then when I plugged it back in it blew the fuse in the PDC. I ran to Autozone and picked up a couple 40A spares, as soon as I plugged the new fuse in it blew the fuse again. I swapped the wires back around, but when I plugged in the second new fuse, it also blew instantly. So now I'm stuck with no air at all.

What am I doing wrong? Little bastards are $5 each so I don't want to blow too many more...

Bah... turns out I'm a moron and wasn't paying enough attention! I swapped the wires in the 3 wire connector, not the 2 wires that run from the controller to the blower itself. Oops. Guessing I fried the control module, hopefully that's all I messed up.

Tried a 250cfm marine blower...

Jabsco 12v 250cfm flange mount blower lines up easily...dont waste your time. looks like a glovebox mounted turbocharger.

Also taped the ducting and fixed recirc, as well as cut a bigger factory intake. Then went to diffrent blower setups.

Next stop: Rear AC

This is a great thread with a lot of useful information; I've replaced my blower motor a couple years ago when it blew with a rock-auto one and it brought me back to the standard crappy performance of an 02' WJ. I'm going to check on all the seals and check on the motor fins to see if I should reverse my wires.

I have small kids that ride in the back and it gets nasty hot back there during summer. I've been using Walmart-type battery powered water spray bottles hanging on the roof handles to help cool things out; cheesy but better then nothing. Hey kids wanna go on an offroad adventure?......(kids)....umm in that sweatbox no thanks dad. If I ever get time and am feeling creative I'd be all about putting in a backseat AC system to really make me proud of owning the WJ.
