The contact owns a 2008 Chevrolet Impala. The contact stated that while driving approximately 35 mph, the defroster system was not properly defrosting the rear window and was affecting his visibility. The vehicle was taken to an independent mechanic for diagnostic testing and the mechanic informed the contact that the wiring harness had overheated and was not carrying enough voltage for the vehicle. The mechanic also stated that where the connector was located, the wiring harness was smoldered and could have caused a fire. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 61,000.

The rear defroster stopped working. After investigating the issue I discover the electrical harness connectors holding the wiring for the rear defroster(and all other wires) is burnt. , the electrical connectors are harnesses for wiring leading form the engine area, to the rear of the vehicle for all electrical components, including the rear defroster. Visibly you can see the area that is burnt for the rear defroster. The wiring for the rear defroster is not fused, and in my opinion is a fire hazard. While doing research on this issue I discover that other owners have had these issues, and is very prominent in Impala's between 2006 and up. With out a fuse for the rear defroster there is no safety mechanism preventing a short, or burn out of the components, thus creating the potential for a fire inside the compartment of the vehicle, and the rear defrost not to work.

The a/c actuator is making a clicking noise which prevents the defrost system from working properly. It starts to click when the temperature is warm outside but it doesn't do it in the cool temperatures. During cooler temperatures, the car makes a revving noise.
Rear defrost does not work, light turns on but does not defrost rear window.

Hvac system in the 2004 Impala has a problem. The ac compreser runs in the heat only mode at temps as low as 30 degrees. This causes the inside windows to fog up on the inside and if the vech is left parked outside all the windows will fog up. The only way to keep all windows clean is to open one of the windows a little and run defrost with at least half speed. If you do not do this the front and side windows fog up and it is very hard to cleat the side windows. This problem is causing my gas mileage to go down and making it hard to drive when it is cold out. Dealer said it is ok. The manual says the ac sould only run above 40 and only in defrost or demist modes.

Vehicle will not defrost without letting into the outside fumes. During winter months the defrosted will let the outside air and gas fumes into the car. Consumer took the vehicle to the dealer who insisted there was nothing they could do. This vehicle and all vehicles produced after 2001 were made this way.
Heater is on and everything heats up to point where it is unbearable to touch. Can burn your finger if touching it.

Windshield defroster is of poor design, vents are too small to defrost windshield. Consumer has to stop, get out, and clear windshield. Been to dealer twice, cannot remedy problem.

Heat/defrost has failed twice both times flushed and repaired by myself (ase master cert. Mech. ) both in cold weather defrost would'nt clear windshield for proper visibilty gm claims there is no problem with dex-cool in the system and it's my problem not theirs.
Major visability and safety problem caused by defroster/heater failure on most 1996 Impalas due to chemical reaction with new (1996) dex-cool anti-frreeze in heater core causing accelerated loss of heat until complete blockage occurs.
