I HAVE A 1994 CHEVY CAPRICE CLASSIC WITH A 4.3 LITER ENGINE AND MY HEAT IS NOT WORKING IT BLOWS COLD? I REPLACED THE ENGINE THERMOSTAT LAST YEAR OR SO THE HEATER CORE HAS BEEEN REPLACED ALSO NOT SURE ABOUT THE WATER PUMP WHATS WRONG WITH THE HEAT? HOW CAN I CHECK IF THE THERMOSTAT IS GOOD AND THE HEATER CORE IS GOOD? ALSO WHEN DRIVING THE LOW COOLANT LIGHT COMES ON AND OFF BUT THERES COOLANT IN THE RESEVOIR I'M CONFUSED HELP! I ALSO HAD TO REPLACE ONE OF THE HEATER HOSE COULD THAT BE THE PROBLEM?

Your best shot is just replace the thermostat and try flushing out the heater core both ways and see what happens-also check the heater control valve and the air blend door-
