2006 and earlier sprinter chassis, which is what a 2007 view is on, has a tiny plastic crank on the door under the hood that selects between fresh and recirculate air. Open the hood, on the passenger side (fan off) poke your fingers into the opening that is the the cabin air inlet. Is the damper loose and flopping? probably. there is not good fix. part is not available. I wired my 07 view in the recirculate position to make the air as cold as possible. I may have owned it for three years, but know it very intimately.
PM me with your phone number, if you are with the RV where I can talk you thru it.
Edit: OK on rereading, I saw your signature, you have an 2008 view, it's the NCV and significantly different than the T1N series like I had...... sorry no help on this.
