Maybe one of you car guys can help me isolate this problem. 4 door power windows. Driver’s window, lock, and mirror adjust work properly. Passenger side and both rear windows and power locks don’t work, either from the master driver’s console, or the individual power lock on each door.
Also the side mirror adjust works for the driver, but when flipped to R it fails to adjust the passenger side mirror.
Question: Is there a component of some type which would be common to all of these problems? Any suggestions?
Thanks
Not necessarily. A typical design for the windows has main power (and/or ground) going into the master switch, then from there out to the other three doors. If that output wire from the master switch is broken, the other windows won’t work. Presumably locks could be the same.
Sometimes a broken wire problem can be confirmed by holding a switch down (say, to the right front window) while moving the driver’s door back and forth from 10% open to 90% open. The ends of the broken wire might touch momentarily and activate the window for a split second. If that test doesn’t produce results, the next thing is to peel back the sheath over the wiring bundle and visually inspect all the wires in there. A broken wire may be totally apart, or it might be broken inside even though its insulation hasn’t come apart yet. Almost always the insulation will at least be cracked.
Getting the wiring sheath loose can be difficult. One end is anchored somehow on the body, the other end inside the door. Usually the body end is most accessible. The alternative is to slit the sheath, but taping it back together is tricky and not as reliable as having an uncut sheath.
P.S. – I assume you’ve checked, but do make sure that the window lockout button is in the correct position. I don’t think that’s your problem, but it makes sense to cover the base.
Ok, the window lockout button doesn’t light at all. But, I’m think that even if that were depressed, shouldn’t the driver’s switch still operate the windows? I thought that the lock button just disabled the other window buttons.
Just a thought. Could that master switch be bad? Did as you said with no luck…
I’ve seen some that work as you’ve described, and some that disable function from both the master switch and the other door switches. Depends on the design.
Yes, though that wouldn’t explain the mirror problem.
I had this problem where only the drivers door power equipment works.
It is caused by a splice under the driver’s seat. Spice #S302 where the input from the drivers door module to the other door modules connects. It is one of those cheap ass splice that should be outlawed. Moisture gets in it and corrodes. Cut back the wires till you get the good stuff and redo it the right way.
Splice S302 can be found under the carpet about six inches before where the wires go up to the drivers seat. It is in a plastic wrap and tape. I believe the wires for the window are brown and white.
.
If so, gently pry it off with a butterknife (it is wider and thinner than a screwdriver;))
and lift the control out of the door. Make sure all the electrical plugs are secure on the control; your problem may just be a loose plug.
If the control’s electrics/electronics have died, you may be able to just go to the local junkyard and dig out the control from another GM vehicle for about 20 bucks.
Actually the wires were brown and tan on mine. You were right on the money with this one. Took me awhile to find it, but there it was. I put the proper splice on it and the windows and everything else took right off! I would have never figured this one out by myself. THANKS HARRY!
I just got done fixing this exact problem on my 2003 pontiac bonneville! Thank you guys! I took out my drivers seat and poked around for a bit till i found the splice. However the wires in my car were light brown with a white stripe (both of them). I would have never thought to look under there you guys are a lifesaver!
So is your car a 2000 Pontiac Bonneville?
If so read the thread above.
If not, how about throwing us a bone here and give us a year, make, model, and exactly what the symptoms are.
I left my crystal ball at work.
New Member here! I just had to join to keep this thread alive! I have lived with this power window issue for several years. Backs haven’t worked at all and recently the passenger side was intermittent. After some research I discovered this thread. It gave me enough information to search a little deeper. Today I went and tackled this problem without much trouble at all. Took a little time to identify the splice, but I did. Just like mentioned above. Everything on that side is working fine now!
It is quite wet under my carpet. I’m not surprised by that but it was more than expected. This damn car has leaked since the day I got it used in 2007. I’ve seen A LOT of water in the rear drivers floor and it soaks all the way up to near the petals. I can’t find the secret, as sometimes it’s not an issue. I’ve read a thread recently about the sunroof drains, but I’m not sure I have it in me to tackle that. At this point I’m just excited to having all windows/locks working properly again. This car has also developed an issue blowing cool air. Won’t do it. My gut tells me after a little research I’ve got some sort of damper/flapper in my vents not working properly. Not sure I’ve got that task in me either.
I have the exact issue in my daughter’s 2003 Pontiac Bonneville SLE. I have found, cleaned, and re-spliced the two wires under the driver’s seat. This has correct the problem with the front passenger window and the remote mirror on the passenger side. The rear windows still do not work…any other good advise on how to fix?
The problem was the only power window, door lock, and mirror that were working was on the drivers door. After removing the drivers seatand lifting the carpet I located the splice approximately 6" from were the seat air bag sensors go through the carpet closer to the drivers side. It appeared that the tape that was used from the factory in the splice was corrosive and corroded the splice on the beige with brown stripe wires. You can see where all 4 meet. I extended them and spliced them together and everything is good to go. Great find. I would have been days trying to locate the splice.
I too have had long standing leak and now the chickens have come home to roost.
I have no door locks, mirrors or windows anywhere.
It has been intermitent, but now the drivers window is stuck half way down.
Last time it came up a bit, kind of stuttering, then froze.
Also noticed a couple relays in the rear electrical center were warmer than the others.
So I likely have a short.
Hopefully the relays are all OK.
I think I have felt the splice about 5-6 inches behind where 2 wrapped wires go up into the drivers seat. ie towa4d the rear passenger bench.
But I do not know how to remove the carpet.
Does the drivers seat and the rails have to come out? My seat is electrical.
How does one remove all that trim around the doors and the sills both front and back on the driver’s side?
Any insight welcome!
This is a great thread!
I’m the guy that started this thread 11 years ago. It is that splice under and to the rear of the driver’s seat. That year Bonneville had an issue where the drain pipes around the windows would get clogged with leaves and debris causing (for some reason I cannot recall) water to pool under the carpet in the rear seat in an area that would cause that splice to short.
I didn’t fix it for a while (until I came on here) and the water had infiltrated so bad that the ceiling cover started to fall, and the entire car smelled like a gym locker. When I pulled everything up there was standing water over the splice and I had to shop vac it out.
