download
CONDITION SUMMARY: Situation: The outlet temperature of the climate control system may not be able to be lowered from either the driver or passenger face and side vents; there may also be an extreme difference between the driver and passenger sides. This issue may be caused by a fault within the Dual Coolant Control Valve (DCCV) or the Dual Automatic Temperature Control (DATC) or an electrical circuit fault. Action: In the event of a customer concern of the above, refer to the Diagnostic Procedure outlined below to assist in determining if the fault is electrical or mechanical. DIAGNOSTIC PROCEDURE 1. Verify A/C compressor operation, refrigerant charge level, and system powers and grounds. 2. Start engine. 3. Using the Dual Automatic Temperature Control (DATC), select: ‘HIGH’ temperature x ‘HIGH’ fan speed x x ‘RECIRC’ and ‘PANEL’ modes 4. Allow vehicle to sit for five minutes. 5. Using the DATC, select: x ‘LOW’ temperature 6. Allow vehicle to sit for five minutes. 7. Using a suitable temperature gauge, record the outlet temperature from both the driver and passenger air distribution vents. Recorded temperatures should be 7qC (45qF). 8. If the recorded temperatures are within 6qC (10qF? of each other, the climate control system is operating normally and no additional diagnosis is necessary. 9. If either of the recorded temperatures are greater than 45qF or the difference between the recorded temperatures is greater than 6qC (10qF?, continue the Diagnostic Procedure. 10. Shut engine off.
