My driver window motor is stuck on in the going down position whenever the ignition is on. If I hold up on the switch, the motor will stop but wont turn the other direction. What I'm wondering is how the control circuit for the auto roll down works, I suspect this is what is not working. I assume it uses a limit switch but I couldn't find one. I would like to try and fix it without spending money or just disabling it before I resort to buying another switch unit to see if that fixes it...

 

This is all i got for you.
