I have the crimeshopper 4 windows rollup module and can get the front 2 windows to roll up but nothing i do will allow the rear windows to roll up. I think this is in part because the rear windows are controlled over the PCM (jeep computer) unless they are being rolled up by their respective door. I have tried everything - any help is appreciated.

Try wiring the roll up AFTER the Jeep module. That should do it. You might have to run longer stretches of wire to each door.

Brian,

I would use a meter to check to see if the back door leads are in fact getting their respective voltage to operate the windows. If not..I would guess the module is bad. Other then that Im stumped! Sorry man!

I tried doing the same thing a couple months ago, Could never get it to work, Almost had it but every time you started the jeep, it would roll down a rear window (sometimes both) an inch or even all the way. Very weird system. After a while I just put it back to factory. Front windows were easy.
