It seems that my A/C compressor clutch will cycle on and off regardless of selection choice (i. e. heat, a/c, defrost etc... ) and independant of temperature selection. I do believe that compressors are supposed to cycle in the defrost mode and obviously in A/C operations, but is it normal to have it constantly cycle in all other selctions and temps? It has been doing this since I picked up the vehicle. I have not addressed this issue to the dealer yet. Thanks for your feedback. -frank.
