Drive an 1998 GMC Jimmy with around 172,000 miles on it (I know this is a lot of miles). Had the local GM dealer work on my rear defroster (one of the clips fell off). After receiving the vehicle back from the dealer I turned my defroster on about two weeks later. The back window exploded like a shotgun after about 15-20 seconds. Dealer says rear defroster voltage regulator must have went bad. I argued that a fuse should had blown before an explosion took place. GM complaint department also disagrees, saying that the vehicle is old and things like this happen. Luckily, no one was standing by the rear window when it exploded because it probably would have killed them. If I'm wrong tell me I'm wrong but I believe GM is responsible for no only replacing the window but fixing the rear defroster voltage regulator. I hope this is an isolated case but maybe by reporting this I can prevent someone from getting hurt (including a GM technician).
