My truck runs fine until I turn the heater on and then it stalls. What could be the possible cause.

MY GUESS IS WHEN YOUR PUTTING THE HEAT ON, YOUR ACTUALLY PUTTING ON THE DEFROST, WHICH IN TURN TURNS ON YOUR AC COMPRESSOR. I WOULD BET YOUR AC COMPRESSOR IS SEIZED SO WHEN YOU TURN ON THE HEAT, THE AC COMPRESSOR IS TRYING TO ENGAGE THUS CAUSING THE TRUCK TO STALL. YOU CAN UNPLUG THE AC COMPRESSOR AND TRY IT AGAING TO SEE IF THE PROBLEM GOES AWAY.
