  Potentiometer Assembly, yh1532

• Description:

  The temperature control switch, also called the temperature blend potentiometer, is the rotary sensor behind the dashboard climate controls that tells the heater and air conditioning system how far to move the blend door, setting cabin discharge temperature from cold to hot as the driver turns the temperature knob. It mounts to the manual heater and A/C control head. On the 2000-2004 Ford Excursion it governs blend-door position for the front climate system. Common failure symptoms include a temperature knob that no longer changes the air from cold to hot, air stuck on one temperature regardless of knob position, erratic or intermittent temperature response, or a knob that feels loose and spins freely. This genuine Ford potentiometer assembly is the correct service replacement and supersedes earlier numbers F81Z-19C733-AA and XC3Z-19C733-AA, so it also services trucks originally built with those numbers. Installing the matching factory switch restores accurate, repeatable temperature selection and correct blend-door travel. It is a direct-fit component that plugs into the existing control head wiring without modification. Verify your vehicle uses the manual rotary temperature control before ordering, as electronic automatic climate systems use a different assembly.
