Clicking sound in dash

Every couple of minutes I hear a clicking sound (similar to a relay) behind the dash...

Hard to pinpoint exact location but it sounds like where my left knee is when I'm driving. At first I didn't think anything of it, but I was sitting at a train crossing earlier and heard it a few times so I figured I would inquire.

I hear it while driving or idling. Park or in gear.

I do have heated mirrors... not sure if that's a relayed on/off or not. Figured it may be that.

Anyone else hear similar in their Jeep? Anyone know what it is?

Could be a blend door or temperature actuator too. Next time it does it, switch your temp knob from hot to cold or switch your vent mode setting to another spot. See if the clicking stops.

Usually it's 1 click. I'll give it a shot though. I didn't notice when I turned the fan off while typing the original post I didn't hear the noise. You might be on to something.

I'll see if I can get it narrowed down further with your advice. Thank you
