Default dual climate control issues

Hey guys,

So I have a 2005 GMC Sierra SLE 4X4 and am having a weird issue with my dual climate control. every so often when my A/C is running all of the sudden it will start blowing hot air out of the drivers side vents but the passenger side still blows cold.. Most of the time I've found that if I turn the key off and restart my truck, it will fix the problem until next time.

Anybody have any ideas what is going out that would cause this and what I can do to fix it.

Thanks in advance!

probably you're blend door actuator acting up, or the computer that controls it.

x2 actuator is pretty common on those.
