Cars affected
Saab 9-5 M04 -
LHD: from and including Vehicle Identification Number 43010217
RHD: from and including Vehicle Identification Number 43013833
Background
The air mixing damper (heater damper) shaft may crack at which temperature control operates unsatisfactorily. This may also be intermittent.
The diagnostic trouble codes B2295 and B2495 may be generated (up to and including Vehicle Identification Number 43014440).
In many cases the air mixing damper shaft is only cracked in the outer end to the stepping motor, and can then be repaired using this method.
Consequently, repairs in accordance with TSB 854-2411 ed. 2 (US/CA) or 854-2396 ed. 2 (other markets) respectively are not necessary.
In the case of customer complaint the air mixing damper shaft must be checked in accordance with the following method.
Symptom description

Procedure
1.
Clear any diagnostic trouble codes using Tech2.
2.
Start the engine.
3.
Select panel setting on the ACC panel. Check that the panel vents are in the open position.
4.
Wait until the system has stabilised (approx. 30 seconds) and then set the temperature to LO on both the driver's and passenger side.
5.
Use your hand to check that air is flowing from the panel vents.
6.
Select defroster setting.
7.
Wait until the system has stabilised (approx. 30 seconds) and then use your hand to check that air is flowing from the vents above the dashboard.
8.
Repeat the check in accordance with steps 3 to 7.
9.
If the air flow is not changed but still blows from the same air vents then the fault is in the air distribution damper. For remedy see TSB 854-2461
(US/CA) or TSB 854-2450 (other markets) respectively.
