I have a 2011 Acadia, and problem with AC
For two years the passenger side was blowing hot air, driver side and rear were
fine. With the hot weather upon us I turned on the AC to find both driver side
and now passenger side blow hot air, rear still works. We checked for leaks,
none. We added some freon, system appears to be working, not sure why it is
blowing hot air(140 degrees recorded).
