I have changed about all the AC Actuators in my 2003 Envoy XL.
this helpful thread and illustration were very helpful.
Last summer my driver's side AC stopped blowing at all. No air. The passenger side worked normally.
I thought I would have to change an actuator.
Then it healed itself and the rest of summer I had cold AC on both sides.
So winter comes and it still blows cold all the time. No heat at all. Still, the passenger side works normally.
Is that the driver's side temp actuator?
I think that one was changed but not by me. A GM tech I found did it for me.
I want to say I always bought AC Delco actuators but they fail at the same rate as the dirt cheap Chinese replacements on ebay. The last one I needed was about $8 on there. Worked the same as the AC Delco one, still from China. It just goes to show that brand names have been deprecated by all the global manufacturing. You can't really say brand names matter at all. Not anymore.
