I am a mechanic and I own a 98 Venture with the same problem.
GM blew it on the window regulator design. The regulator is cheap and designed so it bends very easy. Fix is to replace the regulator. Regulator is a metal sissor like contraption that links the window track to the motor. There are 4 ends on the regulator. One to the motor, two to the window track and one to a plastic frame that screws to the door frame. The problem is the end that goes to the frame is missing a wheel that would allow the regulator to move smoothly. Without the wheel the regulator just scrapes in the frame and allows the regulator to bend. GM just put in a cheap stud that scrapes its way along a plastic raceway in the regulator frame. Very crude and built to fail. Shame on GM. That is why Japanese are beating us to death.
I changed mine myself and it bent again in a couple of weeks. Had to go to Chevrolet to get it fixed $200. Works okay now.

These GM vans are notorious for having a problem with water leaking into the cabin on the passenger side floorboard under the carpet, which is just where the wire harness is. This causes the wiring that controls the power door locks to corrode and short out. I haven't made this repair myself yet, but I have heard several people describe it as being an easy one to do. Just pull back the carpet on the passenger side front floor, inspect the wiring for damage and splice and repair it if needed. Then the locks should work properly. As for the leak, it is usually due to a leaky seam under the passenger side wheel well that will need to be caulked with waterproof sealant. Hope this helps us both!

According to Edmunds' TSB finder there is a TSB "040864014" from July 2004 "REVISED WINDOW REGULATOR REPLACEMENT. ( NHTSA ITEM NUMBER - 10012095 )" which showed up in a search for my 2003 Montana. The title is ambiguous. It could mean that only the instructions in the manual were changed or it could mean that there are new parts. If there were new parts, then maybe they have fixed the problem?

It does not sound like "laker_42's" problem is a short circuit. It sounds like it is operating the way it was intended to operate. This would be a safety feature to keep kids and pets safe. I have no opinion if it is a good idea or not. I have no kids or pets, and rarely have passengers.

Hi Vinray89, tell me did this problem cause doors to lock and unlock when driving? Is this wiring harness corroding causing these locks to short out? Please respond thanks,

I had the same issue with my 1999 Venture and it was indeed the switch. the best way to know for sure is to run a 12 volt power lead wire to the hot or positive terminal on the window motor and then ground the other terminal to a good metal ground. If the motor operates when power is supplied, then the motor is good and the switch is bad. If the motor does nothing, I would replace the motor first and then the switch if necessary.

I have not had that problem myself, nor have I read of anyone else having it. The only problem I am aware of is that it makes the power door lock switches on the doors inoperative. Are your locks locking and unlocking while the van is in motion on the road? That sound like it could be an electronic issue tied into the transmission or neutral safety switch. When the van is put into gear, the doors are supposed to lock automatically. Then they should unlock when the vehicle is in park and ignition turned off.

I am faced with replacing either the regulator or the motor assy (or both) in my 2000 venture tomorrow. It has been bad for a few months but was waiting until the weather got better. The passenger window operates crookedly and erratically from either switch. It makes a somewhat rapid thud-thud-thud-thud when it gets to the top and the switch is still pressed. The noise stops when I release the switch. It has managed to stay up for the last few months and I have not used it at all. I was afraid it would get stuck.
Anyway, I need to investigate it tomorrow. I suspect like Russ23 says that it is the scissors like regulator that is bad, but I want to get it apart first to be sure I have ALL the parts I need before attacking the job. I would've thought the the drivers window would've failed first as it gets much more use than tge passenger window. Is this a difficult job?
The GM shop manual doesn't give a real good R&R procedure for it. Does the assembly come as a whole? Or are there two separate assemblies? IE is the scissors assy attached to the motor etc? I have seen both advertised on the internet separately. The manual also mentions a special tool J-38864 Counterbalance spring removal and installation tool. I know I don't have access to one of these. Do I really need it? Can I make the repair without it? Can I fashion one?
If anyone has some step by step R&R procedures, or some tips or shortcuts, I 'd love to hear from them. Thanks..

Yes, these switches commonly fail. I'd recommend a new one; OEM or Non-OEM.
That's what mine did twice on a 97 Venture. Each time it's the switch.
They are on Ebay or Car parts places new in the $50 range, delivered. Seems like a very poor design; but it is easy enough to switch out.
