Nissan Repair Questions? Ask a Mechanic for Answers ASAP
hey there, thanks for the question.
Thee a/c resistor won't have any effect on the compressor clutch. just the blower motor.
If the clutch is not engaging, its very likely that the freon is low. Have you had the system recovered and vacuumed to inspect for leaks?
have you performed the auto-active test to check the circuit for the compressor?
Heres th eauto active test.
if the test works adn clutch engages, we know the fuse and relay are fine.
Then you can worry about getting the freon checked.
