I've had my 2008 Impala since March 2014, and I've yet to have my rear defrost in working condition. I feel like this a constant complaint so there should be something done about this when there is over 400 complaints made about this same issue. It is very uncomfortable to not be able to see out your rear window cause of frost and when you wipe it with a cloth that is no help neither because it goes right back to being fogy. Help

While driving I noticed rear window was still covered with ice, the rear defroster was not working although the switch was on and light was illuminated, after that I searched internet sites and found that a connector on the passenger side has commonly burnt up so I checked mine and sure enough it is, another guy at work has the same thing on his Impala, currently car is at dealer being insp but they have said so far they won't cover repair, this is a fire hazard inside the passenger compartment of the car.

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.
