Ive read about problems with the window regulator on Dakotas. Heres the issue. I can roll down the passenenger side window from the drivers side with not problem. Cant roll down the passenger window from the passenger side................most times. Today it worked fine..............for a couple trips to town. Tried it again and its back to the same problem of not being able to roll it down from the passenger side. WTF is going on....

 

It does not sound like a window regulator problem.

The passenger side door switch could be faulty - so could the lock out part of the drivers side door switch.

Check for power at each switch.
