Window motor The right rear window motor has stopped working. If I had a wiring diagram I could confirm if the motor is getting the power. DO you know the pin layout in the connector? Thanks, Mike [email protected]

Could be the motor too...could also be the regulator or broken wire inside the black rubber boot from the body to the door .. What's the big deal about pull the door panel ? Take's 5 min's ,no problem . All other windows work ,correct ? The yellow wire ,pin H at the switch connector is battery voltage supply to the driver switch. Don't forget to check the ground side of the circuit . Pin G black wire goes to G 301 , pins A & E go to the driver door window motor . dark blue & brown . Does the passenger window work from the driver switch ?

First you must pull off the trim panel and expose the mortar and wiring to the motor, then test for power and ground, if present test the motor.

Go to Pontiac dealer and talk to service manager. Most of them are willing to print out the page that has the info you need.

Under system click on body & accessories ,then under subsystem click on power windows . click the search button then the blue link . looking at the diagram i see a 30 amp circuit breaker powers the windows , wouldn't think that to be the problem . Check out the ground # at the bottom right . G-103 or 105 . Check some of the thing's not working . Go back to the first part an click on HVAC under system . Check the blower motor circuit . This has a different ground . probably not that ! Checking the instrument panel electrical harness an connector's . Go to electrical distribution under system , then under subsystem click on power distribution . Look an see where all these system fuse get power from , a main fuse , ignition switch or a relay etc.... Check to see if B+ voltage is at the power window circuit breaker when not working . If not , problem is up stream from there . Watch these video's Electric Testing Techniques You Need to Know

Testing the electrical circuit's is the way to find the problem . Hope i explained this good enough . Good luck & god bless

What fuse ? BATT 3 40amp. under hood fuse box ? Did you check G403 ? Free wiring diagrams here http://www.bbbind.com/free-tsb

well you can try "jumping" the correct wire to see if window got up or down... this will tell u if switch is bad... but I would just go but a new master switch... try that before you cause more damage..

Dear FixYa

I found the problem to the window not working. It was due to a pinched wire in the wiring boot between the right rear door and the frame. I didn't have so great an experience with my assigned mechanic. I'm not sure he really ever completely read my posts, nor the results I was reporting. He did provide a wiring diagram that was helpful, but he unfortunately had no influence on the solution.

Thanks.
Darren

this website is great for retrieving wiring diagrams.

check for inline fuses. wire that will melt if theres to many amps running through it usually under the hood. hope this helps
