did you ever get this figured out. I have one in the shop exact same issue, except it has knob control. it was here a couple weeks ago and I changed the cabin filter and blower motor cause they were junk. then it started acting up exactly like described, only defrost really worked, then after messing with it and driving everything else would work for a bit. I ended up diagnosing the actuator, ordered the part, just installed it, everything worked great for about 5 minutes now I'm back to defrost only.
