My 2001 Taurus is not getting any warm air in the heat position. Was previously working. Engine temperature gets about 1/3 up from cold. However, no warm air. Any suggestions on what to check

Check for a defective thermostat.

If the thermostat is stuck partially open, the engine has a hard time getting to full operating temperature. This results in little if any heat coming out of the heater core.

You may have a stuck open thermostat or a plugged heater core.

Other possibilities are a faulty blend door in the heating duct or bad switch.

Check the two heater hoses first. They should both be hot.
