The contact owns a 2000 Pontiac Bonneville. In April of 2005, the air conditioning failed in the vehicle. When the air conditioning was reactivated, it made a loud noise and hot air was dispensed. The contact took the vehicle in for repair and was informed that the motor could not take pressure from the air conditioning being activated. The contact paid for the repair; however, the air conditioning still does not work. In addition, the rear passenger side window and the front driver's side window fail to roll down. The window failure has been occurring for the past three years. The VIN and mileages were unknown.

I've had 8 failures where the power windows fall down without warning. The first two failures were under warranty. Since then he regulators had to be replaced at a cost of $200 to $250 each. I stopped using the power windows years ago but they still keep breaking. On the last two occurrences I glued the windows closed with construction adhesive. Probably not the safest thing to do but I'm done paying for a factory defect. One broke and fell down when the door was closed, five broke and fell down while driving and two broke and fell down while the car was parked.

Passenger window regulator failed. Two months later, the driver's side failed. Costs of over $400 & over $500. Between these dates the transmission went with only 60,000 miles. Cost to repair was $2400. Called Pontiac on it. They had the dealer send a $400 "good faith" check. No more general malfunction vehicles.

2 regulators for two different windows were replaced within the first 2 years which was covered by the GM warranty. The third window regulator was replaced after the warranty expired at the cost of $350. Now the fourth regulator on the last window is broken and the dealer wants over $400 to fix.

Both rear windows have fallen to their stops. They are currently being held shut with clear packaging tape. Both windows failed within 2 months of each other. The second window failed on christmas eve night 2005 when my son just shut the door. GM wants approximately $1000 to fix both. The sad part is that we don't even use the rear windows. GM claims there is no problem.

July of 2005 left front window regulator failed. Replaced window regulator. November 2005 left window regulator failed. December 2005 right window fell down while driving because regulator failure. Car has air conditioning and windows are not used much. Rear window switches are locked out from drivers control because of a child in back seat. Reason for not being used much. I only have fixed the drivers window because of the expense and need to pay tolls. I have contacted GM about covering the parts and I will perform the install. They refused because of the 100K miles. This car is a 2000 Pontiac Bonneville.

The contact stated he took the vehicle to a dealership to have it serviced on February 14, 2003. At that time they had to replace the intake manifold and flushed the motor. On October 7, 2004 the contact took the vehicle to another dealership to have the vehicle serviced. They found anti-freeze was leaking into the engine. The intake manifold needed to be replaced. On December 22, 2005 he took the vehicle back to the dealership to be serviced. Again the intake manifold gaskets needed to be replaced and the repairs were made. The window motor and regulator were replaced. Updated 02/07/06.

Three of the four windows are not working. The cable assembly for the windows does not work. It is poorly designed, made of plastic and is not able to withstand much use. The plastic spool is not able to wind the cable that pulls the windows up or down. Two of the three window are the back windows and were rarely used. Only passengers in the back are infants.

There were no events leading up to this failure. Both rear windows just suddenly quit working. We took the vehicle to the Pontiac dealership and, of course, they repaired them. $300 per window. Sounds a little much. I've noticed several other vehicles, same year, same model have had same problem. GM should absorb some of the expense, wouldn't you think? we have loved this vehicle up to this point.

- Hendersonville, NC, USA

There are no events leading up to the failures. Three windows in this vehicle are inoperable because the motor quit. Initially, the window will either not go up or down and then all of a sudden it will work. One window has had the wiring clipped because I couldn't afford the part. The other 2 we just don't use.

I purchased a GM certified 2000 Pontiac Bonneville in May 2002. Since that time I have had to replace 3 window regulators in the vehicle, one for the drivers door and one each for the back doors. This seems to be quite excessive for a vehicle that is only 5 years old & has less than 80K miles on it. Further, I have a small child so I can count on one hand the number of times that I have lowered the rear windows. I am confident that this is not a wear-and-tear issue, since I have replaced both regulators with GM parts and as I stated seldom roll the windows down. I have noted an approximate date for the first incident below. The most recent replacement was in August 2005.
