Window Motor Regulators

[Julieandjim]

I'm really curious to know if anyone else has had to replace any of the window motor regulators in their Grand Prix.

I'm on window #2 at $460.00 a pop. Last time it was the drivers window and I was told it just wore out. This time it was a back seat passenger window that probably hasn't been down a dozen times since I bought the car in 1999....

Love my GTP, but at 40,000 miles have had to replace 2 window motor regulators, THE TRANSMISSION, the air conditioning unit, and repairs to the moon roof shade that just decided to stop sliding one day.

Wow dude. That's quite a bit to go wrong at 40K miles. Hope it was all covered under warranty. I like the GTPs, have driven a few at work. The new Comp G's look to be sweet too, but I haven't seen any yet.

As for the window regulators, never heard of them going so soon. Water leaking into the door maybe? Keep an eye out on eBay, things like that come up often, and you might be able to save some $.

Window Motors are one of the things that many GP owners have replaced often along with the tranny.

Ive never had to replace the Window motor, knock on wood, but am on my 3rd tranny.

Try searching www.clubgp.com on possible causes on the motor failures and used motors.

Window motors and the regulators can be purchased together or seperate. Buying just the motor is cheaper now because you don't have to buy the whole reg/motor assembly.

Mine was broken for 3 years. I wasn't about to pay $319. for the part. I found one for $185. Just fixed it yesterday. The problem is the design. It has a metal braided cable that raises and lowers the window. When you stop the window during up or down movement the cable will fray causing it to lock up.The design looks good on paper but........... Remember that the dealer is there to make big money. P.S. It wasn't hard to fix. A couple of bolts and an hour of my time. Also had trany fixed.Burned out second gear.$1,625.00 (ouch)

Replaced the passengewr one on my 98 GP....I did it myself. I think the part was 145. Must be a common design flaw.

Recently the rear passenger side window in my moms 2002 Grand Prix wouldn't roll down, then it started working and hasn't stopped since. But last week the passenger side window stopped and still hasn't started working yet. Fortunately they are covered under warranty.

I have a 2000 SE and I have two motors that are down. Both of the Passenger Side Windows are shit. The entire panel on the drivers side door has been replaced on top of that. My twin bro had a 99 SE and he had the same problems....

I have a 1998 GTP and have just recenly replaced my 9th window regulator on my car. I still have 3 broken ones that I am now waiting to see what Pontiac Customer Assistance will do. I refuse to spend anymore money on these things. It cost me around $500/window. It is absolutely ridiculous. The problem is due to several factors, bad design is definitely one of them, but heat (if you live some place where it is always hot) affects them as well. It is a known defect according to several service managers for GM, but they will not recall it since it is not a safety issue. I have had no other problems with my car other than the window motors, but it is enough to sway me not to buy another one. I was also informed that this problem is not just limited to Grand Prix's and that GM still uses these window motors in their 2004 models. It is ridiculous to pay this kind of money to fix windows (3 of which I never use) If I had any clue how to repair them myself, I would.

I have a 1999 Grand Prix (purchased new) and have had to have 4 motors replaced so far... seem to average about 1 or two a year which is really annoying. Some seem to go in pairs, and even those windows that I've maybe rolled down once or twice for the life of the motor! If anyone has a step-by-step guide to replacing these motors/regulators, please do broadcast to the list (I saw that tschic43 in this thread replaced his in a couple hours... hint hint... ) :o) Please share the wealth if you can... thx.

I work on these cars for a living my shop does 50 cars a day and we may change 10 regulators a year!! SO I feel that it is not a major problem but it only affects a small percentage of cars.

[GTPgirl]

I don't know if that's what my problem is, but both of my back windows have started whining loudly when they are rolled up or down. I generally use all of my windows, I open my sunroof and roll all four down a couple of inches, or I'll roll down just the back ones a few inches. I don't want to have to replace those, I've already got to replace my exhaust and possibly my power steering pump. I don't have the money!

Mr. Moderator, you just don't want to hear about the problems, but I know 3 other people and they have all had to replace a couple of window motors, the service manager at the dealership I go to in Arizona told me that it is a known defect and GM has done nothing about it, but they get anywere from 5-10 cars a day with that problem. It is not affecting a small percentage of cars, it is affecting any cars with stock regulators in them.
