My 96 Blazer wasn't kicking out any heat, so I replaced the thermostat earlier in the week and heat started coming out again. Now, when the temp gauge gets near the red line (which never used to happen), the heat turns cold, and I have to turn the heat on full blast for the gauge to come back down and the heat to start again. Drove it last night and had no heat at all, although the temp gauge was fine throughout. Coolant is full, but something is obviously wrong. Ideas?
