I had this same problem and it turned out to be a simple fix,my problem was the hot wire contact on the blower itself.Fix was cleaning the contact w/sandpaper and replacing the part on the hot wire that connects to it.

I had the same problem on my 2004 GMC Yukon XL.
Still under warranty the shop was able to reprogram the climate control system and tell what was wrong rather quickly with a OBD computer.
That’s when they found both of the climate control (driver and passenger) side actuators were bad and the control unit that tells the actuators where they should be was also bad.
The truck was in the shop with most all the dash, seats, consol, and steering wheel out for a week. The cost was over $1200.00.
That has seamed to fix the problem. Good Luck.
