SOURCE: 1998 caddy sts over heating and blowing cold air when heat is on

sounds like it might be low on coolant. Low coolant levels will stop the flow and circulation to the heater core, and also might be the cause of overheating

SOURCE: air and heat not blowing air through vents

Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.

A/C Blows warm when idle


I can't say much without having the actual code.
When the ac stops blowing cold at idle, the most common reason is not enough air flowing thru the radiator, or the radiator fan is not running and the only air flow is when the vehicle is moving.

My heater won't blow warm air if i am parked only when the car is moving


If your engine temp reads warm then your heater core is clogged. Try flushing the system. If it reads cold then u need a new thermostat

I have a 2000 Chevy Venture van and the heat when turned on blows cold. For a while it was still blowing out warm air thru the back vents but now it is all cold. The van wouldn't warm up at all e


needs the water system back flushing out, heater being cold is its blocked up some time a few back flushes and forward flushes with a hose pipe should free up the dirt inside, same with the engine and radiator. there are meany videos on you tube to help you understand how to back flush you engie. but do the radiator and engine and heater separate so the muck does not go back into the engine.

I have a 1999 Caddac DeVille . The AC works fine during the summer but in the winter it won't blow out hot air unless I'm driving. I've let the car run in the morning to warm up but the inside...


your heater core is possibly stopped up if there has been a radiator leak and stop leak has been poured its definetly clogged or could be a faulty thermostat

AC blowing heat and air at same time


Yeah Ron, the flap that covers the heater core is open and when you're moving the air is pushed over the heater core and into the cab your in. Possibly just a vacuum line of that controls said flap. Check all vacuum lines for good proper connection to these flaps because all of them are vacuum actuated.

Heater blows cold air from top vents after running for 1.3 hours


Sounds like you may be able to fix it by flushing your antifreeze and back flushing the heater core. Some car owners cheep out and put stop leak into the antifreeze, others dont change there antifreeze at all. Both are mistakes.
