Fault symptoms
The temperature in the rear of the cabin does not agree with that set on the ACC unit.Conditions
The rear heating damper in the heating and ventilation unit in the Saab 9-5 is controlled by a linkage from the front passenger heating damper. The design of the linkage and the rear damper means that in some cars and in some driving conditions, the air admitted to the rear of the cabin is too warm compared to that in the front of the cabin. This phenomena can arise when different temperatures are set for left and right-hand sides along with certain distribution settings. The temperature in the rear of the cabin can be too high even if the passenger panel vent is closed.In addition, during winter, the rear of the cabin may be felt to be cold in comparison to the temperature set on the ACC unit.
Procedure
Change the rear cam. Refer to Warm air in rear, VENT . For the part number for the service kit, refer to the electronic parts catalogue (EPC).This project is supported by memberships and donations. If you use this site, please consider Joining SCNA and/or making a donation.
