Weird sound coming from a/c

I got a 2003 ford expedition. When i turn on the a/c in the rear I hear a clicking sound coming from the back passenger side. What is it...

One of the actuators in the rear panel is bad...they're $25 and it's 2 of them...I suggest changing both since u have the rear panel off...10 minutes to remove the panel and 5 minutes to change them out...only held by 3 screws...search rear a/c in the forum...this had been talked about extensively with part numbers and pics

My front and rear went out at the same time. Front requires dash removal. I understand it's a problem with the Expy.
