I've noticed that my A/c compressor clutch is clicking all the time whether the a/c is on or off on my 02 Ram 1500. Is this a sign of it going out or does something just need to be adjusted or what? Any help would be great thanks.

 

A/C compressor cycles on and off if you have the A/C on and also does it when you have the Defroster on as well.
Do you have the defrost on?

 

No, everything will be off (a/c, defrost, everything) and it always clicks
