rear heat not working

[rebs]

I have a 2003 Yukon and the rear heat worked last winter after I had to set some controls and I do not remember what I had to do. I can change the outlets and change bloer speed, but no heat.
Does anyone have any idea's on this ?
Thank you for any help

Make sure that you have the rear control in the off or manual and then adjust it by the front control I am not at home but that is how i have mine.

My kids love to play with but buttons so i made it to where they are unable to mess with them any more and i have control over there heat they get.. if they piss me off they get to freeze if they are good then they get heat lol.

Let me know if you get it if you need me to grab some pics i can do it when i get home from work.
