Q: Fan Motor running when a/c is on upon start up.

asked by on May 29, 2016

I noticed yesterday upon starting the Yukon within a few seconds I could hear the fan motor running real fast. The a/c was on when started up. So today I started it with the a/c off. I could see the two fans were not turning when I turned on the a/c they started turning making the loud noise that fans make. Can you advise? Thanks, Kim
