I been reading since the first post. Seems like everyone has the same issue, hot on drivers side, cold on passenger.
My issue is the opposite. Cold on drivers, hot on passenger. It's been this way for a few years, never cared before cause I never sit over there.

After trying all the easy fixes, it remains the same. Which of the actuators do I need to replace? Some of the pictures in this thread no longer show.

2006 Z-66 Avy. Blowing Hot Driver, Cold Passenger.

I removed my 10A AC Fuse from inside the cab fuse box, for about 1-min. Fixed for now.

My 2009 did this yesterday on the way to work.
AC on, blows ice cold on passenger side, hot on driver side.
After work, on the way home, was working correctly again.
Still good this morning.  :cautious:  

My 2009 is doing this again.
Except this time it is cold driver's side, warm passenger side.  :rolleyes:

The rolleyes smiley isn't working.  I'd roll my eyes at that, but it's not working.  :p

Chef Dave i had that same  problem in my 2003 avalanche on one side hot the other cold two different temperatures what works for me is on the hot side i put the temperature knob on to 82 on the cold side i put the temperature knob on to 60. I?m not saying it will work for you but try it anyway and oh yes check the ac fuse and follow those instructions if needed.        G C

Good morning Gwyn. The thread you are replying to is quite old, the last post was in 2016.
Coincidentally I had this  issue on Friday. After disconnecting the battery to weld a nut onto a broken bolt, I had hot air on drivers and cold on passenger when calling for 60 degree AC. I shut the truck off and restarted and luckily all was well again, and has worked for the last 4 days without issue. I guess my problem was the actuator had to re-learn, but not exactly sure since it fixed itself.

Installed my lower hvac actuator today…the one on the passenger side just above the transmission hump. It has worked perfectly today and that maddening click is gone! (y) I got an ac delco off Amazon for $49. I tried pulling the fuse reset but it only worked for a day or two then it would go back to heat on the left and cold on the right but the clicking never went away. I took the old actuator apart and the grease had piled up on one end and might have hindered the movement causing the clicking noise of the gears trying to push through the pile of grease…IDK. Anyway, it’s 50 bucks well spent IMO! I’ll post back if this one goes south but I’m happy the clicking is gone and I’m cool so far!
