Hello. I have been driving my truck and lately or even when I first bought it I hear like a clicking noise from the A/C vent to the left of the radio making a loud clicking noise only when the A/C is on high. When I shut the vent the clicking noise stops. When I set the A/C controls to a lower fan speed it the clicking is not there. It could be a clicking noise or even a knocking. Does anyone know what this may be? I am just curious so it does not develop into a bigger problem. Thank you in advance.
Also sorry if I posted this in the wrong part of the forum.
