It is a 2014 Wrangler JKUWelcome to Wayalife... Is it a car or a Jeep?
You actually just remove the glove box if I'm not mistaken. Check YouTube. Somebody has had to of done it there.
There is a blend door actuator and a recirculate door actuator. Unfortunately, it sounds like you need a recirculate actuator which is much harder to replace than the blend. I have heard you can do it without removing the dash but you will have to remove the seats to get under the dash or rig up some way to hang out the side of jeep. Also, it's an absolute nightmare. I tried a few years ago and gave up after a few failed attempts. I just unplugged it so it doesn't click anymore and the only difference I notice is the defrost sucks now because its stuck in recirculating.It is a 2014 Wrangler JKU
