Question about 1999 Chevrolet Silverado 1500
Your heating system is run by your cooling system. If your cooliant is low then you are not going to get adiquiate heat disapation to your heater core. So check the entire cooling systerm. Your water pump (low flow), hoses (leakage), you already checked the thermostat & heater core. So other than that I don't know.
