I have seen these issues on the W body Buicks, and the N body GM cars as well... Same goes for the H bodies... GM went to the cable design for the window actuator... Its by far the crappiest design I have ever seen... And the dealership locally knew it was a problem... Heck they didn't even have any in stock, because they were replacing too many... I just shook my head... Even the local junkyards told us that they couldn't even hold onto the regulators... They all break...
I just had BOTH of my rear windows drop down by themselves one day apart from each other. I only have 20k on the car and I am the only driver. No one is ever in the back either. I can't believe how poorly they are made! Now I have to see how long it takes to get them.
it'* a common problem for Bonneville P/W motors and regulators to die an early death.My 2002 SLE had one die at 32,000 miles.Just a word to the wise- a common source of water leaks on these cars is due to the door panels being removed to repair the windows. Under the door panel is a weather shield (clear plastic) that seals the door-when these are removed to service the windows, they frequently are not reinstalled correctly-very very common occurence.Thjis causes water leaks on the floorboards.The leaks unfortunately don't show for quite some time.The carpets can be wet underneath, and it will not show up on top until they are saturated- maybe months later.If you have had your windows repaired (seems like rear is most common)-I'd recommend popping the plastic trim off at the carpet edge and sliding your hand under the carpet and checking for dampness.I usually remove the rear seat bottom to check also.To remove the seat bottom- give a sharp rap with your fist at the bottom front in the middle of each foot well-hit with a rearward blow-it should then pull up.It may take a couple of hits to get it to pop loose.The trim can be pulled straight up and usually removes easily-pull carefully and you shouldn't have a problem.To reinstall, line up the white plastic clips with the holes in the body and give a GENTILE rap with your fist on the trim panel over the clip.Occassionaly the clip will stay in the body when removing the trim-if so pry it off the body will a pair or wire cutters .Don't squeeze to hard unless you want to buy new clips at your local dealer.
Well it finally happened! number four died today. now at 73K miles all of my window motor regulators have failed. this is crazy...luckily i think i have about 2 or 3 hundred miles left on my extended warranty.
GM really needs to do recall on this or have them ready for replacement for free!!
the thing that really bothers me about this is that i KNOW within the next 50 to 70K all four will probably fail again and i will have to cough up the cash to replace them as the warranty will have expired. this is a faulty part and we should not have to continually pay to replace something that is known as a bad part.
