Question about 1999 Chevrolet Silverado 1500
After letting the truck warm up properly i only get a burst of warm air then the air blows out cold--i had a new thermostat put in last fall--what could be the problem? Is their a heat sensor on this truck, if so, where is it?
Heater core could be pluged up, try flushing it out, it could have sedament build up restricting flow into heater core. Also make sure its full of coolant.
