    Customer Concern: No heat and code 23 in the Automatic Temperature Control (ATC) system.
    Tests/Procedures: 1. Check for voltage across the driver wires (Brown/White wire and Dark Blue/Red wire) at the blend air door actuator while running a self-diagnostic test. To run self-diagnostics, press and hold the floor, mix, and defrost buttons for 3-5 seconds.

    2. If at least 10 volts when going through the diagnostic test, but no change in temperature, the actuator is faulty.
    Potential Causes: Blend Air Door Actuator

    Tech Tips: Code 23 is for the blend air door actuator.
    Diagnostic Codes: 23
