Temperature Setting Does Not Provide Comfort

The following areas should be checked and adjusted, if necessary, when comfort complaints occur.

1. The Air Mix Door Adjustment
2. The In-car Sensor Aspirator Hose
3. The Temperature Adjustment Potentiometer in the Programmer
4. The Sensor String

Check to ensure that the in-car sensor aspirator hose is attached at the in-car sensor and the aspirator. Repair the aspirator hose if it happens to be kinked.
