Heater problem
1997 Lincoln Town Car V8 Two Wheel Drive Automatic 175000 miles

Can you tell me where the heater control valve is located on a 97 Lincoln Town Car 4.6 L? Is it under the windsheild wiper motor?

Do you
have the same problem?

Most heater control valve are attached to the heater hose/s. I look for yours but not listed having one. The question is what's wrong?

The heater is blowing cold air. I have the manual which in troubleshooting section says it would be the thermostat, the coolant level, or the heater control valve. I have eliminated the first two. I bought the part at parts store but don't see the same part under the hood. Any suggestions about where it would be?

Try warming the Vehicle, then carefully feel the heater hoses, are they both hot? If one is cooler than the other, You need to flush the core, or a replacement job on the heater core.
It's possible that the temperature blend door is stuck. The shaft it swings on is metal, and over time they tend to rust and binde up, operated the temp knob while you look for or feel for the actuator that moves that door, some actuators ar vacuum operated, some electrical. Either these motors, called servo motors can go bad or the above mentioned issue! If the shaft is frozen, try a small drill bit at the base of the shaft, drill thru the plastic and spray some white lithium grease in there, if you can move it by hand, so much the better! Work it back and forth till it moves freely!
Try this press off and floor at the same time, then within 2 seconds press auto, if it comes up with a fault code post it here.

Merlin2021 I did as you prescribed, pushing the buttons that you mentioned. There was a pause with a little light going around. Then I heard a clicking noise in the dash. Then the numbers 024 and 025 began flashing. Wait it gets better. Then I turned off the car and turned it back on and the heater started working. AWESOME! Now I don't know if the problem is fixed, but hopefully this information will give you a better idea of what my problem is/was. Thanks man!
