Hey fellas i had a few questions on the two actuators that control the hvac heater/ac system on my 03 c5.. 1st question is:is there only 2 actuators? 2nd question is: Which actuator controls what? I have seen pretty detailed pictures posted by a member on here of where they are located and I was wondering which side controlled what. Thanks in advance fellas. I have posted picture im referring to.
Are both that you are pointing at electric or are you also asking about the vacuum actuated one on the right with the red/yellow vac lines?
I'm not positive but I think the right and left hand temp mix is electrically operated, I think that what those are. The red/yellow vac diaphragm is for heat and defrost.
Are you having problems with the HVAC?

Thanks for the reply 03whiteconv, I was asking about the electronic actuators. My car does not throw the air out of the top vents it seems like it throws air from the bottom and maybe from windshield vents. Maybe my problem has to do with the vacuum actuators instead of the electronic ones
