A/C blowing hot

[custom99]

My a/c is blowing hot at all locations. I tried recharging and it did not help. I need suggestions where to start checking and testing. 03 Yukon XL

try your actuator, which you will have many, or the resistor under the passenger side in the front.

i have the same problem...even my heat doesnt work in the rear. ive heard the recirculation actuator may be the cause for the front (which i dnt kno where its located)and there are two actuators for the rear that are to be upgraded...i also just recharged my system with no luck...

How do I check the actuators or resistors?

When it happens are your sure it is blowing hot everywhere? Make sure the passenger isnt blowing cold still. It is most likely your blend door actuator. If you restart does it start blowing cold again or is it hot all the time?

Have you recently had your battery die or changed it?

check to see if the belts still on the air compressor mine broke off and 6 months later my air compressor went out

is your a/c compressor even coming on? my compressor isnt even getting power...as soon as i find where the recirculation actuator is and find a place to buy one thats what im goin to try to fix mine

I am not sure the compressor comes on all the time. I was under the hood and my son turned a/c on and I could hear it kick in but not sure if it actually does everytime I have tried. Always going down the road when I try it. I'll have to start by checking that first. The belt is definitely on.
