My son has a 1999 oldmosbole 88 with the V6 3800. Great running car. No joking...it only has 74000 miles on it. So as the title states, the AC blows cold out of the 2 drivers side vents but blows warm out of the 2 passenger side vents. I've never experience this before. Any ideas what this problem could be? And do you think it's a large repair bill?
