#127 of 213 1999 Pontiac Montana Power Window Problems
Feb 13, 2010 (10:36 pm)
The 2 power window switches on the driver side do not work on the drivers side front window nor on the passenger side front window. When you push the button(s) nothing happens. Now if you press the passengers side window switch - the window goes down slow and only moves about an inch then stops. What could be the problem? switch(es)? motor? Where should I start the troubleshooting process? Before the windows stopped working on the drivers side, the windows started to work slower than normal. You would have to press the window button, then depress the switch and press again to get the window going - but then it completly stopped working.

The problem turned out to be the instrument cluster which had to be replaced. I called GM on my parent's behalf and they worked with us on an equitable compromise. I was pleased with the good customer service we received from GM.
#129 of 213 2002 Pontiac Montana Electrical Issue not addressed
Feb 27, 2010 (9:18 am)
On here they talked about dash lights out, blowing fuses, not running lights, and chimes going off. We checked all the previous post and did not find the problem, Finally found a new problem that was causing all this and a fix for it. In the left rear fender well under the car by the air compressor if you have one, there is a connection for the towing package if you have one installed. We found this towing package control box from Drawtite had shorted out internally and melted and burned, there was a burnt smell in the area. It is winter and lots of snow here. It also burned wires in the area but were only for the towing connection. The fix, if you don't need to tow anything just unplug and remove the 6 to 9 foot bundle of wires going to the trailer connector and tape up plug in connector. It you tow things, you need to replace all of it.

#131 of 213 Help with driver's side window switch
Mar 13, 2010 (12:22 pm)
This switch broke this morning leaving window in down position. I heard a cracking sound (breaking plastic) when I tried to open the window. Clearly the switch is broken and I'll replace it. Can anyone suggest how to close the window (what connections to bridge on the cable?) I am reluctant to just hook a jumper between two points that I think are right; the switch unit has electronics and I'm just not sure how to proceed.

I would simply jump the middle post of the bottom of the switch to one of the posts beside it.
I cannot say which post but dont keep the jumper on too long when testing in case you have the Window down post.
A scrap yard will have a good spare part.
You can indeed safely do this.
#133 of 213 electrical issue with 97 pontiac montana transport
May 16, 2010 (3:28 pm)
Ok so I have been told (without this person looking at it) that my current problem is a fried wiring harness. This is what's going on. All of my taillights and turn signals have stopped working. When the turn signal occasionally works, the clock and thing that tells me what direction I am going also blinks in time with the signal. When I step on the brake, both of those lights go completely out and the turn signal arrows light up on the dash until I take my foot off the brake.

Sounds like the dreaded rear tail-light short problem. This has been discussed several times on this Forum.
The tail-light bulb SOCKET shorts out...between the black power lead and one or more of the other colored wires. The GM supplier used plastic that would not tollerate normal heat. Solution: check bulb sockets for melted / smelly plastic....cut out that bulb socket and replace with a new one....not a used one from a junk yard.....there may be more than one bad socket. Use a new bulb also. Hope you are good with electronics and repairs. Be advised that there are almost 300 Recalls and Technical Service Bulletins on that type of vehicle.
#135 of 213 Flashing dash board
May 18, 2010 (1:20 pm)
Not sure how this forum works - but I have a 2000 Pontiac Montanna and when I turn on my lights, the dash board flickers - strobes really. Anyone else have issues like this?

Yep... same thing happened to me. There is a TSB on it and I replaced a screw on the side of my alt (that is accessible only by feel) that is about 2 mm longer than the one that you take out. Find the TSB and you'll find the proceedure and part you need. No garantee that it is this, but it was for me. $6 part. I'd have to say that when I did it it worked 100%.... after 3 years it occasionally does it but no where near what it was. Before you attempt yourself be certain you have the skill - I don't take any responsibility for you dropping the screw in the alt or misthreding, etc which could be very very expensive to repair ! My 2 cents anyway.
