Auto Glass: 1996 Aurora - power windows dont work, power sunroof, window regulators


Question
QUESTION: Question as i have replaced one power window motor and nothing. I have a 1996 Aurora and not one power window works as the power sunroof on the same circuit does. I have checked the switch on the drivers door and plug going to the motor, 12 volt up and 12 volt down per wire. I replaced the power window motor on the drivers side and the same, nothing. Now I see power fed and the regulator must be holding the motor from working? I just purchased a drivers door regulator from ebay and I will check that. Why are all the windows failing and why is the switch sending 12 volt when pushed and the motor isn't working? Is this a case of all the regulators failing or just the master drivers door? Any answers will help

ANSWER: Hi Charles,

It is highly doubtful that your window regulators are the problem.  You can prove this to yourself by connecting a spare 12 volt battery directly to the window motors.  The window motor will move the window up or down depending on how you connect the positive/negative wires from the battery to the window motor.  You can reverse the wires from the battery to get the motor to run in the opposite direction.

I am not an expert when it comes to an unusual electrical problem like this one.  I think you are going to need someone with significant experience in auto electrical work to diagnose this issue.

Sorry I couldn't be more helpful.

QUESTION: Ok, I ran a ground directly from the battery to the motor, motor getting power not working, changing the drivers regulator. The gear must be stopping the motor from working

Answer
Hi Charles,

Did you supply "power" from the positive battery terminal or use power from the switch?

Before you go to all the work required to replace the regulator, I suggest you remove the motor from the regulator.  That will allow you to move the window up and down by hand and you will be able to examine the regulator to be sure if there is something wrong with it.
