I have the typical clicking sound coming from the dash, figure it's the actuators. Thing is there is three of them, I just wanted to know if all three are the same thing? I've found actuators that are 'air inlet' and 'defrost'. And then one that says it isn't HVAC at all. All I need to know is if I need to purchase three of these things so I can replace the actuators. Thanks for any help

 

Just buy the one you need. I thought there were actually 4 but I can't remember. I do know that one of them is different.

 

There's 3 on the pass side, and one on the driver side which I believe is the different one?
