Troubleshooting

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 at a workshop. We recom-

mend that you contact a Saab dealer.

Note

When the A/C system is running, the intake

air is dehumidified. The resultant condensa-

tion that forms on the evaporator is drained

off under the car. When the car is parked,

this may result in a small puddle forming on

the ground. The warmer the air and the

higher the relative humidity, the more con-

densation will be produced.

Inadequate cooling

1 Check that the condenser (in front of the

radiator) has not become clogged with

dirt and insects.

2 Make sure that the compressor drive

belt does not slip (see page 215).

3 Check the fuses for the ventilation fans

and compressor (see page 235).

Maintenance

• The compressor drive belt should be

inspected under the regular service

program.

• Clean away dirt and insects from the

condenser and radiator to prevent clog-

ging. When washing the car, use the hose

to spray the radiator and condenser

(located in front of the radiator) from both

sides (both from the front of the car and

from inside the engine bay). Do not use a

pressure washer.

Caution: Do not hose down the radia-

tor and condenser while 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.

• Applicable to the manual climate control

system - During cold months the air condi-

tioning should be switched on once or

twice a month and run for 5–10 minutes

during highway driving once the engine is

warm.

This action saves the gaskets in the

compressor from being spoiled. The

WARNING

• All repairs and adjustments to the A/C

system must be carried out at 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 gas can cause eye injury or

other personal 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 R 134a with other refriger-

ants.

NOTICE

Do not use a pressure washer when

cleaning the condenser or radiator due to

the risk of damage.
