Replaced thermostate . fan is working great
Check coolant level first if full try removing heater hoses and flush heater core with a garden hose both directions...only with a garden hose.....this vehicle may have an electric blend door motor..with engine running change from hot to cold...listen for any movement under dash...that will tell you if the blend door is working regardless or how it is controlled

Well, you probably need a heater core. I it is a 93. Find a friend to do it, and buy a manual for it. The car is probably not worth, what you would pay a shop to do it for. But check prices...

SOURCE: heater core replacement
OK, Ifound the problem with mine. Dont unplug your air dryer. I checked the 2 hoses coming out from the heater core and still one was hot and the other not hot. The top one comes from the radiator fill tank and the bottom one comes out of the core and goes around to the front and into the water pump. I disconnected both close to the core and could runwater through both directions so upon further examination, I disconnected the hose at the water pump and no water flow. The hose was plugged up with something. Once I cleared it with a hanger and reconnected it I had water flowing through the core and great heat. Hope this is your problem too as it is aneasy fix

it sounds like the thermastat needs replacing .it might be worn .so it is not closing .check the heater hoses .if they both are hot the heater core is blocked
