I diagonised my whole ac system about 5 days from a mazda dealer. They say they have tested whole system and it was runing ok. I just used my ac yesterday in a parking position which when realize a clicking sound constantly every 10 to 12 sec. When I looked inside it was ac compressor motor stopping and running again. ( I dont hear that sound when on traffic light or while driving and also when engine is not running while ac is running.) Is it normal or something to worry about . When I tried to call the dealer they say I need to book in for next week and also have to pay another fee for diagnosis.
Any help will be appreciated.

Thank you!!

 

The AC compressor clutch will cycle under normal operation. The clicking sound is the clutch re-engaging.
If the compressor ran continuously it would eventually blow up.
