A/C TROUBLESHOOTING PROCEDURES

摘要

The A/C system does not operate in a vacuum (no pun intended); it is reliant on other systems to operate at peak efficiency also. 1. The cooling system should be inspected and tested. Follow the vehicle manufacturer's recommendation for flushing and replacing the coolant. Test that thermostat opens when it's supposed to and that the radiator cap maintains the correct pressure. 2. Test that the cooling fan(s) or fan clutch engage and disengage when they're supposed to. 3. Inspect and replace worn belts and hoses as a failure here could leave the vehicle stranded.
