1998 Ford Escort Question: Heater Blowing Cold Air
I have a 98 Ford Escort. I have taken it in to 2 dealers. Both have told me that a blower switch was stuck on cold. They switch it to hot and replace then it stops working after 2-3 weeks. What do I need to do to adjust the switch myself until I can afford to have it looked at more closely? - jhog
A blower switch controls the fan speed, not the temperature. Are you having a problem with the blower fan operation, or the temperature controls? - Bret Bodas
The hot-cold adjustment knob adjusts the TEMP via a cable and some gears at each end of cable. The far end of this setup from the hot-cold knob is a round wheel (gear) that connects to a shaft that apparently mixes hot and cold air. The round gear is located on drivers side, under dash, about mid lower leg area. If yours fell off while in COLD, then thats what you get, cold air. Mine just pulls off from shaft with no resistance. - Desert Dweller
The hot air stopped working on the heater. The fan is working, but it's cold air.
My heater is not blowing out hot air when the car is sitting still or idling a light you can smell exhaust fumes
All the heater does is blow cold air. It does not make a difference what temp it is set on. I know it is not low on coolant, blower works, and the A/C still works. I can not get hot air to blow.
heater blows cold air only, new thermosat
