A/C
We bought this Yukon about 2 weeks ago.
Everything has worked fine until 2 days ago. First
the a/c on the passenger side stopped blowing
cold air. Now when you crank it, it blows out cold
air on the drivers side for about 10 seconds then it
goes straight to hot without touching any of the
controls. I can hear something under the dash
switching just before it starts blowing hot air. They
had just replaced the battery before we bought it
cause the other battery was dead. Any help would
be greatly appreciated. Thanks in advance.
