Try bringing the engine up to normal operating temp with the heater on hot, feel the two heater hoses going through the firewall and see if both are hot, if they are then you more than likely have a blend door or blend door actuator problem. If one hose is hot and the other is allot colder then you probably have a stopped up heater core.

Probably not. What temp does the car/engine normally run?

alomar721

It doesnt give a temp degree. it is somewhere between half way and 3/4 on the temp gauge.

I don't think it's a thermostat problem. Check what I posted above.

I have a 98 Sable and I had to clean out the heater core a few years ago.

I checked both hoses and one is hot and the other is a not as hot but it is warm. so what do i do from here.
also can I do a radiator flush will that work.

I would suspect a clogged heater core. You could try flushing the core & see if that helps. It don't always work though. Unhook both hoses and flush into the side that was only warm and flush backwards. Easy on the water pressure. You should get all kinds of gunk out of the core.
