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 in operation, mois-
ture from the air will condense on the evap-
orator. When the car is then parked, this
condensation will drip off the evaporator
and form a small pool of water on the
ground. This is normal. The warmer the
ambient air and the higher the humidity, the
greater the amount of condensation formed.
Inadequate cooling:
a Make sure that the temperature and
air-distribution controls are in the
appropriate settings, see page 77.
b Check that the condenser (forward of
the radiator) has not become clogged
with dirt and insects.
c Make sure that the drive belt for the com-
pressor is not slipping, see page 179.
d Check the fuses for the ventilation fans
and compressor, see page 189.
NOTE
• 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.
• All repairs and adjustments on the A/C
system must be carried out by a Saab
dealer authorized for this kind of work.
• Never mix R134a and R12 refriger-
ants.
WARNING
• The A/C system is pressurized. Do not
break any connections or undo A/C
system components.
• Escaping refrigerant gas can cause
blindness or other injury.
