Heater control clicking

[OL' BLUE]

Hey guys, has anyone had a clicking noise when they changed their heater control from Outside air to research I’m getting a clicking noise over by The glove compartment area. I’m running a 2013 pro 4X. Could use some help with this

A clicking when the fan is running? Does it change with fan speed?

Check your cabin filter. Debris may have gotten by it into the blower fan
