Diagnosing A/C not recirculating on mac

[TX87R10]

Hey everything has been running good in my A/C until a few days ago the max setting no longer seems to recirculate air.

Does anyone have a link to a good diagnosis thread here? I tried searching around but no luck yet. A/C blowing, it's cold, just feels like the door to recirculate is not operating

On mine, there is a noticeable difference in the sound of the air when on Max and the door switches from fresh air to recirculate air from inside the cabin. You can definitely hear it change from ac to max ac. If it stopped recirculating, I'd be looking at the vacuum line and the pod that operates that door in the passenger kickpanel.

Yeah definitely the sound is not happening. I couldn't figure out the best way to explain that lol. Will check there first thanks!

I pulled the kick panel and tested and the blend door is not working of course, then I had the bright idea to test other modes and realized it's not going in to defrost or anything. Going to do some more research but figured I would share I. Case it's something obvious

Just kidding I found it. Traced the vacuum line back and find it snipped at the tee
