From the driver's seat when i push the left rear window switch UP, it will not go UP automatically. I must hold the switch down to get the window to go all the way UP, WHY? Aaand when the window does finally get alll the way up, while i hold the switch down, you can gear the window motor clicking as it is slipping, when the window is all the way up. Of course the dealer said i need a regulator and motor, but the motor does drive the window up smoothly and the window regulator seems to be runnining up and down smoothly. One delaer said it is the comfort control box located in the trunk. Aany ideas/ thx, mike 602 616 2974 in phoenix,AZ.
