The air conditioning systems on some 2005 Saab 9-7X models may be slow to cool in high temperature/humidity conditions.
According to Saab, the problem usually is intermittent, surfaces right after engine startup and is most prevalent during low engine and/or vehicle speed conditions.
Insufficient airflow through the condenser due to a slipping electro-viscous fan clutch likely is the cause of the malady. Installing an improved fan clutch assembly, part NO. 15293048, is the simple remedy.
