- If temp guage reads normal, the lack of heat may be due to the Heater Control Valve. Located in front of the radiator. Lower passenger side. A real bugger to replace.
- The plastic cap just over the thermostat is key in re-filling the anti freeze and bleeding air.

It sound's like one of two thing's, first open the glove compartment look behind to the left you will see a clear vacuum line going to a goldish in color accuator remove it once the vehicle is at normal operating temp. if you get heat then you have a problem with the vacuum switch, just plug the vacuum hose, you will have to reconnect it in the summer to get the AC working. The other problem could be the heater control valve, located under the hood inline on the hoses going to the heater core, upper passenger side of the fire wall.

Hello Callahan5922....this sounds like a stuck blower motor resistor. I assume the blower won't function in the a/c mode either? If you have a digital multimeter you can check this. I believe it's fuse #2....if the digital indicator goes up or down when you increase or decrease the fan speed thats good. Locate the blower motor resistor....you wil find it located on the fire wall behind the right valve cover hiding behind the heater hose, it's about the size of a cigarette pack. With the engine off, and key in on position, turn the A/C on High, and rap a tap tap tap on the resistor. You might be suprised when the blower motor takes off a runnin,
I hope this is the answer you need and i was able to help solve this for you. Good luck...

Relays are normally located under the hood in a protective plastic box. Good Luck Ned
