My Yukon has a whole new cooling system. AC blows cold air. Recently it has started blowing hot air. I am assuming it is the blend door actuator. The part is cheap, but its getting to it that I am unsure of. Does my whole dash need to come out or is there any easy way to get to the actuator? Any tips??Please!!

I hate to see you pull the whole dash out and come to find out, your A/C stopped working. Just for giggles, can you verify that the A/C is indeed working? Verify the A/C compressor is cycling on and off.

Im pretty sure it is, im no mechanic though. Compressor and accumulator are not even a year old. Its random when it blows hot air. Air will be on working fine, i drive somewhere, turn the ignition off and when i get back in its blowing hot air.

you should be able to view the actuator under the dash and see if its working

Compressor is working!

Thanks for the tip on viewing the actuator!
