Three problems related to defogger heater have been reported for the 1997 Chevrolet Blazer. The most recently reported issues are listed below.
1997 chevy Blazer has been taken to bob Chevrolet in columbus ohio for back flush of heater core due to no heat for defrosting windows. This has been done twice. Vehicle has been taken to a local sunoco station due to no heat. Had themostat replaced. After that it heated up a short while but not to the point of doing the job during colder nights. I finally took it to a local garage and they said it needed a heater which costs me $500 to replace which I had to have done. I have a couple of friends that have had the same problem with there Blazers and the heater cores going bad. I think this is an issue and should be looked into. No wonder people buy non american crafted autos. I don't think if so many people with the same type of vehicles are having the same problems that gm should get away with this. Please advise. Thanks, scott bever.
