Couple months ago, went out to the car to drive to work and noticed the driver's window was down that 1 inch it goes down to clear the convertible top's rubber seal when you open the door. The passenger side was normal. Rolled the window down on the way to work and it wouldn't go back up. All other windows worked normally. I did not try to put the top down.
I tried the "disconnect battery to reset the smart window module" as per a youtube video but no luck.
A couple days later, I took the door panel off and removed the whole scissor assembly from the door. I removed the motor / gear assm. from the scissor assm. and turned the key to run (to confirm it wasn't mechanically binding) and without touching the window switch, the motor kept continually spinning in one direction -> down.
I manually moved the scissor to the up position and reinstalled the motor assm, put it back in the car and left the electrical connector off. Window is up at the expense of the driver's quarter window and using the convertible top!
I assume there must be a bottom travel limit switch in the motor gear housing that's gone bad BUT I have no idea how these systems work ... am on the verge of buying a replacement regulator assm. and they are apparently very expensive.
Any information, help, links are greatly appreciated. Thanks!
