New at forums. I have 2013 gmc 2500 that is having hvac freezing issues. After a while of driving I can't change temp, speed, direction, or off. All buttons do nothing. I can turn off truck and turn it back on and everything works again for a few minutes. Went away for few months and randomly came back. Side note the outside temp shows blank lines on dash cluster randomly then shows temp outside. I don't know if this is a part of issue or something else. Thanks for any help.
I am having trouble where when running the heat, it stays warm until truck reaches operating temp and then starts blowing lukewarm air out of all vents. Now, when running the AC, it only works for a few minutes and then hot air comes out of all vents. There are plenty of posts on the internet about air door actuators, but most are suggesting that rarely both passenger and driver actuators will fail concurrently. Therefore, could it be the control module, which would be an easier fix as some of those actuators are almost impossible to reach? Additionally, the air blowing in the back seat is the same as the front if that helps. Thanks.
