need help with the ac on my 2009 silverado
I have a 2009 silverado. The ac on high blows very weak to the point where it gets hot. It's intermittent though sometimes it'll blow high. I can hear a slight wiping sound from under pass dash. I'm not sure if it's a control unit issue or what. Any help from a more technical person would be greatly appreciated

You didn't state it kicks on and off, only that it was weak at high speed. and some times blows hot.
You should take somewhere that they can look the system over.
It could be low on freon.
It could also have a bad blend door motor causing it to blow hot instead of cool air.
If the Blower motor speed is affected, I would suspect the Blower Motor Resistor. Mine started to intermittently die at high speed. Eventually it would no longer work on high.
