Checking the wiring

Check the signal cable between the climate control module (CCM) and the evaporator temperature sensor. Check for an intermittent short-circuit to ground.

Take a reading on the connector for the climate control module (CCM) between terminals #5 (#29) and #16 (#40).

Remedy as necessary.
