My heat works fine when I start driving. When my temp gets up around 220 it starts blowing warm to cool air. My radiator and thermostat is new. I had a leak but the Bars tablets seal fixed that. It was a small leak. The antifreeze is the right mixture. 50/50 right? I know nothing about cars really, and am suprised that the warmer the car temp the cooler it seems the heat.

I am experinacing the same thing... thought changing of the thermostat would correct the problem... but not the case... looking for the fix too...

Does it tend to blow cooler ait when you are stopped at lights or in traffic? If so check your coolant level, it might be a little low.
