B2222 on Jeep by model: symptoms, diagnosis and fix
The plastic gears inside the temperature blend door actuator strip, so the actuator motor free-spins and ratchets. Owners hear a rapid tick-tick-tick from behind the glovebox or center dash for several seconds after startup and every time the temperature or mode is changed, and one side of the cabin (or the whole system) gets stuck blowing only hot or only cold. The failure is common on the MK Compass and carries into the MP; the recirculation and mode actuators use the same gear train and fail the same way. It is a wear item rather than a control-head fault, so replacing the climate control head does not fix it.
Common Symptoms
- Rapid clicking or ticking from behind the glovebox or dash
- Clicking for a few seconds after starting or shutting off the car
- Temperature stuck on hot or cold regardless of setting
- Air comes out of the wrong vents / mode will not change
- Driver and passenger sides at different temperatures on dual-zone
How to Fix
Identify which actuator is ratcheting by sweeping temperature cold-to-hot and toggling recirculation while listening. Drop the glovebox (and on some cars the lower dash panel) to reach the actuator, unplug it, remove the two or three screws and swap in a new unit - Mopar OEM is strongly preferred because aftermarket units often mis-calibrate. After installation, cycle the ignition and let the HVAC module run its automatic actuator calibration, or run the calibration routine with a scan tool.
