No fan comes on when I turn on the a/c.

What is your question?

It is cold around the vents but nothing is coming out and the panel for all the temp/controls is hot to the touch.

What makes this problem better or worse?

nothing

How long has your 2010 GMC Acadia had this problem?

started yesterday, drove from Iowa to Colorado in99 degree heat. It gave out about the last 2 hours of a 10 hour trip.
