Fault diagnosis

If a fault occurs in the A/C system, there are a number of checks you can perform your- self. If the fault persists, however, have the system checked by a workshop. We recom- mend that you contact an authorized Saab dealer.

Important!

When the A/C system is running, the intake air is dehumidified, and the resultant con- densation is drained off through two outlets underneath the floor of the car in the vicinity of the front doors. It is therefore perfectly normal for water to be seen dripping from these outlets when the car is parked. The warmer the ambient air and the higher the humidity, the greater will be the amount of condensation formed.

Inadequate cooling:

aCheck that the condenser (forward of the radiator) has not become clogged with dirt and insects.

bMake sure that the drive belt for the com- pressor is not slipping.

cCheck the fuses for the ventilation fans and compressor.

Maintenance

The drive belt for the compressor should be inspected under the regular service program.

Clean dirt and insects away from the con- denser and radiator to prevent clogging. When washing the car, use the hose to spray the radiator and condenser (located forward of the radiator) from both sides (both from the front of the car and from inside the engine bay). Do not use a pres- sure washer.

Caution: Do not use the hose when the engine is hot.

Other than in extremely cold weather, do not screen the radiator, e.g. with netting, as this will greatly diminish its cooling capacity.

Note:The A/C system will only operate when the outdoor temperature is above the freezing point (0°C, 32°F).
