Clicking sound from A/C

I have a loud clicking sound around the glove compartment area. Around 10 clicks then it stops. Happens at random times while heat/ac is on. Never while it is off. Doesn't matter the temp or speed the blower is in. Also, does not seem to affect the operation.I have climate control if that helps? But again, doesn't matter if its ac,. heat, auto, non auto, temp, setting, defrost, floor or panel vents.... nothing maters as long as its i got the ac going it does this

The clicking is caused by a part called a temperature control ac/heater blend door actuator motor, most likely the door it moves is sticking and the little gear drive inside the part is clicking.

2012 Fiesta clicking sound coming from glove compartment

I think this may be the heater/AC air temperature control blend door actuator motor gears slipping over teeth, this is due to a sticking blend door that is hard for the electric motor to move due to heat warping. Remove the dash and replace them is my advice.

Clicking in dash and no hot air

Blower motor worn and weak, taking time to actually start due to worn out brushes in the blower motor. Change the blower motor. The clicking that you hear is actually the springs that provide tension on the brushes. Sounds like the brushes have fell out, leaving only the springs to provide the needed voltage. Springs rubbing the contacts will sound like a slow click click click at first, but will speed up as the motor shaft starts spinning faster.

2005 Ford Mustang GT -loud clicking noise in audio system

There is a possibility that the cellular phone is interfering with the audio system. Cell phones communicate on their own with cell hubs to change locations, or to receive mails. Try to place the celular in a different position, or to turn it off on a single trip to see if the clicking disappears.
