When turning temperature knob to heat, no heat will be present only ambient temp. Also when switching to defrost air will only come out of center and side vents.
I took a look at the drivers side actuator and it does not turn when turning temp controls and air distribution controls, both inlet and outlet hose from heater core are hot.
I did notice that there is another actuator on the passenger side as well and it does not move either. I do not know which actuator controls what?
All lights are working on the climate control panel, and all blower speeds work as well as the air conditioning.

Only troubleshooting i have done is disconnected the battery for 5 min then reconnected with no change.

According to GM service information the recalibration can only be done with a scan tool.  I am attaching two wiring diagrams to show where the system fuses are.

Thank you very much for the response, i do have a Tech2, things have change for the better, the wife got in the Captiva today and everything worked fine, I checked everything tonight and sure enough, everything is working, but the question is for how long.

Now i wish i would of hooked up the Tech2 last night, but was going to wait until this weekend.

Thanks, one thing though is i found this site, looks interesting and helpful so i think ill stick around.

I hooked up the Tech2 and i could not find anything related to recalibrating the motors/actuators or Climate control related

I believe your vehicle may fall into the “Global A Platform” category and if so a Tech 2 will either not work at all or have limited functions. You would need a GM MDI or equivalent scan tool.
