I am having an issue with the power window motor on my passenger side rear door. When you push the button on the rear door or at the drivers door the motor operation is intermittent. Sometimes the window will work and sometimes you have to keep pushing either one of the two buttons to get it to move an inch at a time. One of my kids opened the window last night and my wife could not get it to close. I looked at it this morning and noticed that if I pressed the button on the drivers door first, then turn the ignition key to on, that the window operated without a problem. This issue is only happening with this one window. Does anyone have any ideas before I take a trip to the dealer (not again). 2000 X Limited 4X4 65K miles.

Thank in advance
