My friend's truck has the sliders too. It's also a 2005. Does the same thing. Have you tried fiddling with the temp setting on the slider? He wiggles his up and down and it goes back to blowing cold for a while.
Also, is it doing it to both sides, or one side? If one side, which side? My friend's does it to the passenger side.
The newer trucks I think have a reset / learn function for the blend doors. Mine is still the old style w/o that. I took some of the actuators apart and fiddled with them... Actually got one working again. The issue is when they age there's a limit switch in the actuator. If it turns too far it will shut off the power connection to the little motor in the actuator. I had to reset that but eventually the whole thing went bad. I was the "limit switch" in the actuator.

My 2005 Tahoe had something similar BUT my recirc door never worked and I never fixed it I could get by without it. Here recently I had symptoms like you mention when it gets really hot outside. Has freon, pressures all good, rear blew colder than front. Changed out the recirc door actuator (I didn't think this would fix it).
So now when I drive around and start to wonder why my a/c isn't blowing cold I realize I didnt push the recirc button, now it is so cold I have to turn it down when it is 90+ outside.
So short story is - does your recirc door work, as in you can hear the difference in the air flow when you turn it on?
