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.
