Q: Constant "clicking/ticking" in the engine compartment when the A/C is on...

[Zim Hosein]

Anyone have any idea what is causing this fairly audible "clicking/ticking" when I have the A/C on? The noise goes away when the "click" of the A/C "clutch" cycles off, then when the next "click" is heard, the noise becomes audible and quite annoying to say the least! Looking at the engine bay w/ the hood open, it's definitely on the left side [passenger side]. Any ideas? If you need any more info, please ask! Thanks in advance for any assistance everyone!

While my MM doesn't do it, my E250 does, it's the AC clutch. Yes, it is annoying, the only fix I am aware of is a new set of clutches.

Thanks for the info Spectragod! Now I hope the dealer has the A/C clutch in stock.
