Stuck air recirculation flap switch

Hi all,

Did a quick search of "air recirculation flap switch" on the 1st Gen forum here and didn't find what I was looking for.

I hopped in my truck yesterday and tried to switch the recirculation switch from "fresh air" to recirculate and it's jammed. It moved about half way and it got stuck. I have push it to one side or the other with a lot of force but it slowly moves back to the center. It feels like there's gum in there or something.

Coincidentally, the blower fan also started making noise but I suspect some leaves may have gotten in there by the sound of it. I'll check that out this weekend. Just thought it was odd that both symptoms occurred at the same time.

Anyone had the recirc switch get sticky on them like this? If so, what was the fix?

Cheers
