POSSIBLE CAUSES
1. Radiator and/or air conditioning
condenser is restricted, obstructed
or dirty.
2. Electric radiator fan not operating
when a/c is on.
3. Engine is overheating ( heat may
be transferred from radiator to A/C
condenser. High underhood
temperature due to engine
overheating may also transfer heat
to A/C components).
1. Has a diagnostic trouble code
(DTC) number 17 been set?
2. Coolant level low.

certain drive line components. One
or more of these shields may be
missing.
