So wife said ac not cold enough. I tried it seemed reasonably cold but not icy cold. Did notice right side blew warm! Researched that. Tried adding freon but my cheap hose with gauge seemed not to let freon out. Gauge read 35 in the green. Next day 88dg wife said blew warm her side! 1 thing she said also fan does not blow very strong. My 2008 uplander same fan deal. Not very strong. On purpose for snowflakes i guess? We bought the dodge last yr second hand private owner. 200k miles. Had a new trans at 170k.

 

You could have a couple of problem, Maybe blend doors are sticking or the recirculation door is not opening correctly. I believe you need to get the minivan into a shop and see what is going on.
