Ok, as strange as it sounds it seems like the amount of air when in recirculation mode is less than it has been in the past. It is definitely less than when in fresh air mode. I would say 3/4ths less. The temp is fine, just seems like a loss of air. My first thought was something caught in the duct under passenger side dash. But, I can't see anything and can't feel anything although I can't get my hand very far up in the there. My question is, has anyone had experience like this? Should recirculation have less air volume than fresh air mode? Are there any mechanical things to look for? Again, temperature is normal, cold so I can't imagine a blend door issue. I'm at a loss. Thanks in advance.
