Heater problem
1994 Ford Thunderbird V8 Two Wheel Drive Automatic

In this vehicle, the heater does not blow hot air. When turned on, it only blows cold air as if the AC is running. I have also changed my thermostat.

What else could it be.

Start by feeling the two heater hoses under the hood when the engine is warmed up. They should be too hot to hold onto for very long. If they are just warm, suspect a plugged heater core. They can often be cleared by forcing water through both ways with a garden hose.
