First, make shure that the water level in the radiator is apropriate, then ck the thermostat for oppening and closing(you wont have a heater if the thermostat is constantely open) ck the 2hoses that suply hot water to the heater core, both hoses must be hot when engine is runing .if one off the hose is cold ,the hot water is not circulating to the core and back to engine .ck the valve , see if you can by pass it and see the results if you have heater , replace the valve. nicolas

2000 caddy Seville ...after starting and engine warm turn on the heater and it blows cold air. Fan works / waiting for hot air and then all the sudden it kicks in. Engine at normal temp


Low coolant, if there is an air pocket in the engine it will make it to the heater core. Once there , the air coming out is cold/cool. Once the coolant fills the heater core, it gets hot. If the coolant is fine hot or cold, then have the HVAC system scanned.

Heater blows only cold air. in and out hose are both hot, what could it be.


The door that mixes hot and cold air seems stuck in the cold air position. Check for a vacuum hose leak.

Replace the temp control on this car, it should be electrical control not cables.
