Pinpoint Test C: The Climate Control Illumination Is Inoperative

WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  1. C1 CHECK CIRCUIT 19 (LB/RD) FOR VOLTAGE 
    • Key in OFF position.
    • Disconnect: Climate Control C294e.
    • Disconnect: Rear Climate Control C951.
    • Place the headlamp switch in the PARK position and rotate the headlamp switch knob fully counterclockwise without turning on the interior lamps.
    • Measure the voltage between the front climate control C294e pin 2, circuit 19 (LB/RD), harness side and ground; or between the rear climate control C951 pin 2, circuit 19 (LB/RD), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to C2.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  2. C2 CHECK CIRCUIT 57 (BK) FOR AN OPEN 
    • Measure the resistance between the front climate control C294e pin 1, circuit 57 (BK), harness side and ground; or between the rear climate control C951 pin 1, circuit 57 (BK), harness side and ground.
