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 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:
a Check that the condenser (forward of
the radiator) has not become clogged
with dirt and insects.
b Make sure that the drive belt for the com-
pressor is not slipping.
c Check 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).
WARNING
• All repairs and adjustments on the A/C
system must be carried out by a Saab
dealer authorized for this kind of work.
• The A/C system is pressurized. Do not
break any connections or undo A/C
system components.
• Escaping refrigerant gas can cause
visual impairment or other injury.
NOTICE
• The A/C system is designed for use
with R134a refrigerant.
• Refrigerant handling requires special
equipment and special procedures for
charging and draining the system.
• Never mix R134a and R12 refriger-
ants.
