Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

clicking sound during a/c operation clicking sound during a/c operation

When turning on the A/C around 65-67-68 degrees, a clicking sound starts. This noise is caused by the A/C Servo.

A quick workaround to remove the issue is to turn the temperature way high to start the "Heater" then go back to your desired cold temperature.

This Clicking sound occurs when the servo got stuck after turning on the A/C either by dirt or lack of lubrication.

The servo is located behind the glovebox, as it can be sen in the picture attached. My recommendation is to replace this part after it starts with the clicking sound, or you can lube it with some WD-40 or clean it with alcohol.

I replaced mine, it cost me around USD$100 and 50 for labor.

Hope it helps.
