As per Jose from Hollywood FL's post above, I had the same problem and his advice helped me fix it:
"The problem you are encountering is a faulty A/C actuator. When you open the rear tail gate, on the right (passenger) side plastic molding there is an access compartment you can get to by popping the top lid (long, looks like a tray). Inside you will have access to the rear A/C unit. There are 2 white electrical cases. One you can easily see and access, and the other is on the left hand side of the A/C unit."
In my case, I simply unplugged the cable assembly going into the far left hand rear AC unit activator, and the metronnomic "click click click" stopped. The downside is that now the rear air only blows from the roof vents, but those can be pointed away or closed by any rear passenger.
Thanks for all the tips. They saved me time and money. We were going to try taking other things apart first. Is it safe to leave the actuator unplugged? Thanks in advance.
I have an 06 expedition. I have the same sound but it is coming from what I believe to be an actuator. but mine is located in the front of the vehicle just behind the radio and a little to the right. It is a white square box. I unplugged the harness coming into it and it stopped the clicking noise. anyways i am hearing a lot in this forum about actuators located near the rear of the vehicle , but not anything about the front actuator. Can any one help?
