I have a 94 Chevy blazer, I believe the heater core is shot, How can I defrost the windows without heat?

Question

I can't put it in the shop right now because I need it for work. The problem I have is that it blows no heat what so ever. I can deal with it being cold, but not having the windows instantly frost up on the inside. Any tricks or ideas to try until I can get it fixed? Does rain-x work on the inside?

Answer 1

Buy a portable plug-in heater that runs on 12 volts and place it to point at the windshield.

More than one heater can be used if you wish,one on the dash for the windshield,one or two on the floor or console for you. Just be careful not to overload any part of the electrical system. these heaters can be bought at some truck stops, parts stores and on E-BAY. I hope this helps.
