I have been fighting this problem for months and I'm looking for any insight to what I might be missing.
The passenger front window will roll down but will not roll up. I have replaced the door switches on both the drivers side and the passengers side. Also the motor regulator. Still the same problem... I thought it might be a pinched wire and I have tested power through the whole system from door to motor regulator. I have also made a jumper wire and have crossed the connections and can get the window to roll up using the down switch so I know it's not the motor regulator. What am I missing here and what can I do to fix it?
