Climate Control System - Diagnostic Procedures
Note. All air conditioning (A/C) related tests should be run in an ambient temperature of at least 10°C (50°F).
- Verify the customer concern by operating the system.
- Visually inspect for obvious signs of mechanical or electrical damage.
- Listen for any unusual noises during climate control system operation.
- Inspect the air conditioning (A/C) system with an ultraviolet (UV) lamp for traces of UV sensitive leak trace dye.

- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, verify the symptom and refer to the Jaguar Approved Diagnostic System.
Inspection and Assembly Requirements - General Procedures
- Check for leaks using ultraviolet (UV) Lamp. Refer to «Fluorescent Dye Leak Detection - General Procedures»(ref-311053-S15874593072009032300000) .
- O-ring seal surfaces must be free of dirt, lint, burrs and scratches. The O-ring and connector should be lubricated with air conditioning compressor oil. Refer to «Specifications»(ref-311053-S05415061362009032300000) .
