The motors should be grounded through the door. However, do both sides work if you run a seperate ground? There could be a bad or weak body ground somewhere.

Both motors worked off car w/seperate battery.I found that the slide on connectors though sliding all the way and snapped into place on the motor and switch, werent making contact. Used slim screwdriver to create an interferrance fit tightening the sliding contact inside both plugs "motor&switch"then things started working still have trouble w/switch only working 1 direction down hot wired to go back up. Replacing switch thanx 4hlp and the reply

Hi. In searching my PW problems I see Mattcon9 had the exact same issue. RF window will only go down from the RF sw and will not come back up. Master sw is new and it won't work RF window at all but works the other 3 windows perfectly. I have 12V from the master sw to the RF. 3 wires total have 12V. Darker blue is constant 12V. The lighter blue is 12V up and brown is 12V down. I've swapped the RF sw with both switches from the back doors. The RF sw will work both rear doors but the is still no change in RF operation. With the motor plugged up when holding RF sw for down operation the brown wire to the motor gets 12V. When holding the sw for up operation both the blue and brown to the motor see 12V. At this point the cancel each other out and so nothing happens. What can be the cause?
