2008 chevy Impala. Consumer writes in regards to window defogger malfunction. The consumer stated he checked the fuse block under the hood and found the defogger relay to be working. The fuse block did not have a fuse for the rear window defogger. He took the vehicle to an auto repair shop, and after hours of investigating and testing, the door trim under the ip fuse box was removed and a 30 amp fuse and holder was found hidden under the trim. The holder and fuse were replaced. Last December the defogger stopped working again. The door trim had to be removed and the fuse holder was replaced.

I had numerous problems with this vehicle (almost through my third set of tires, oxygen sensor going at 46,000 miles, rust beginning at 38,000 miles {car was two years old}, and the battery going prematurely). Last week, I attempted to put on my rear defogger. The light came on, but my rear windshield was still fogged up. The defroster also does not blow cold air if the car is in park.

The rear defogger does not work. Nothing happened, it just quit working. When you push the rear defogger button on the front panel, the light lights up showing it is working, but it isn't working on the rear window. It is hazardous because you can't see out of the rear window with frost and even snow built up on it while driving. I find this a big big problem when I cant go far snow builds up to fast. One other time the wipers stopped for no reason in the middle of my view. When I stopped at the gas station I shut it all down went got a pop came back out and started the car and then they started to work again not a good situation.

Rear window defogger-- when we had a recent snow storm (one of many), I used my rear window defogger (defroster) only to find out it wasn't clearing the window of fog or melting the blowing snow. This prevented me from seeing the vehicles behind me except from my side mirrors. The lamp on the control lights normally, but there is no voltage going to the rear defogger grid connectors (on each side of window). There is no separate fuse going to this device, only a relay in the forward fuse box. The problem turned out to be a burnt pin on the large connector block under the kick panel on the passenger side. As a new connector (both halves) would boost the cost from $261 to $411, at the dealers suggestion, I had them jumper the wire from each side of the connector instead of replacing the connector. (as this connector is there for assembly purposes only, why not jumper it. ) I believe this problem was due to either a poor connection of the pins during manufacturing (high resistive connection) or improper sized pins that are not heavy enough to carry the current. As this connector is not normally accessible to the owner/operator and does not move, it is not a "wear item" and thus was a manufacturing issue. My service writer tells me that this has happened on at least one other Impala that he has seen in his gm shop. Why isn't this power grid fused as it used to be in earlier Impala's? is the pin the proper size for the current going through the pin? this needs to be checked out before it causes a fire in a car. I have a photo available of this connector if needed. The old connector and pins are still in my car.

Failure Date: 10/10/2007

Since vehicle was purchased in 12/04, rear window defroster performed very poorly. In 3/07 it ceased working, however dashboard control switch and I/p control relay appeared to remain functioning correctly. Troubleshooting revealed defective circuit breaker (mechanically broken armature) to be cause of complete failure. Following replacement of circuit breaker, I/p control relay, and antenna module, rear window defroster is back to performing poorly. Electrical grid appears to be functional - good heating pattern (when it heats) with no visually obvious defects. No obvious problems were found in I/p control relay and antenna module that were replaced. Electrical diagnosis indicates excessive current draw thru defroster grid, which causes circuit breaker to trip after several seconds of operation. Manually cycling the defroster control allows breaker to cool and can again be activated to provide 10-15 seconds of repeated operation. Note that electrically disconnecting the grid (at the window) does not cause the breaker to trip, indicating no short in the vehicle wiring harness. With possible exception of the oem circuit breaker, diagnosis revealed to obvious heat damage to any other components/wiring in the vehicle. Rear defroster grid appears to be source of the excessive electrical load in the circuit. Problem does not appear to be addressed in tsbs that I can locate to date. Discussions with several technicians has resulted in nothing more than guesses at this time.

2001 Chevrolet Impala. 2 weeks ago, I had my radio on + clicked the 'rear defrost button'. It caused static in the radio. A couple of days later this was still a problem but now the battery/security/service vehicle soon lights came on in that order repeatedly. I took my car to my local mechanic. He said that the rd problem was known but he could not find the reason why the warning lights were coming on. He checked all connectivity, fuses, ground contiuity,etc to no avail. He reset the computer code + felt this might resolve the problem. We no sooner left his parking lot + the warning lights came back on. He checked it again, and sure enough, nothing appeared to be wrong. He said the problem may actually be in the 'body control module' itself because everything else checked out. However, he did inform me that there was no way to check the bcm + that even the dealers had no way of checking it. So now I'm spending hundreds of dollars to fix a part on the car that may or may not be the problem. I have no choice though since I drive 62 miles a day everyday to work +can't afford to have warning lights come on by default. As for the rear defog problem, there is a TSB on it # 030844005a. My concern is that since my car is no longer under warranty I've been getting quotes of no less than$600. 00 to fix this. My car went out of warranty based on my mileage. I've had it for 2. 5 years. I feel that I shouldn't have to pay to get this fixed. Adding insult to injury, if I want onstar back in my car its another $400. 00. This upset me because iknow the price of this feature was already built into the price of the car so if I want to be able to use it I have to pay for reinstallation. This is wrong. I believe the rear defog problem is a manufacturer problem and if it also effects onstar I shouldn't have to pay for it. It is wrong for the consumer to have to pay for either of these issues regardless of whether the car is still under warranty or not because it's a manufacturer problem.

The connections for the rear window defroster become unsoldered from the windshield at the connection points on the glass. I have seen this on my 2001 Chevrolet Impala and a late 90's Chevrolet luminas.

Rear vision is impared when looking through back glass. The DE-icer/defroster has turned ( foggy) . This is a real safety concern at night especially.
