Morning all.....quick question for you - my Nitro is the 'skinny' version - so not many bells & whistles compared to most of you - but I'm not able to 'close' off any of my a/c vents. I'm curious if this is in all Nitro's? Initially we thought the a/c was a bit wimpy, but truthfully, when moving down the highway, I'd like to shut my vent off and just allow the passenger side to circulate air.....and I can't do it :thk:
