2001 GMC Yukon Question: my heater is stuck in full heat mode & Will reset after vehicle is turned off

my heater is stuck in full heat mode & Will reset after vehicle is turned off -
Answer 1
Sounds like problem with blendoor actuator behind dash. First though I'd disconnect battery for 10 minutes and maybe all will reset. Had problem on my 2006 ford fusion- would not blow thru panel vents but was fixed after reboot. -
