Air conditioning (A/C)
WARNING
• All repairs and adjustments to the A/C
system must be carried out at a workshop
authorised for this kind of work.
We recommend that you contact an
authorised Cadillac workshop.
• The A/C system is pressurised. 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 R134a with other
refrigerants.
Troubleshooting
If a fault occurs in the A/C system, there are
a number of checks you can perform yourself.
If the fault persists, however, you
should have the system checked at a workshop.
We recommend that you contact an
authorised Cadillac workshop.
Car care
233
Note:
When the A/C system is running, the intake
air is dehumidified. The resultant condensation
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 condensation
will be produced.
Inadequate cooling
a Check that the controls for temperature
and air distribution are correctly set.
b Check that the condenser (in front of the
radiator) has not become clogged with
dirt and insects.
c Make sure that the compressor drive
belt does not slip, see page 188.
d Check the fuses for the ventilation fans
and compressor, see page 206.
