For those like me and too lazy to search, here you go! Thanks to Conrad Storz for the video.Thought I'd resurrect an old thread, as I've now solved the problem. RockAuto has a Dorman Heater Blend Door Actuator 604188 for $20.79. There is an excellent youtube video on the Soltice Forum that shows how to remove and install the actuator. Awkward, but doable. Should take about thirty minutes. Word of advice though, kneel beside the car and work with your left hand as far as removing/replacing the three screws. I spent an hour laying on my back under the drivers side dash, before I finally gave up and called it quits. Couldn't see/access the third screw. Went back and looked at the video and saw that a simple thing can make a lot of difference.
BTW, this actuator replacement did solve the problem. I now have all the variations of heat/cold throughout the temperature dial range. I had read on another forum that this fix may be temporary, but so far, so good.
I'm not as literate or forum savvy more lazy, but pass my time pointing and clicking when working my shift.. I know how many forum readers would read something then say why no picture, I know I do, so this one was a no brainer, I didn't even have to make the video!! LolThanks for linking in that video SARBlade. Good to hear you got the problem resolved kplange.
First off, did you do the calibration procedure? -- See: A/C intermittent failure - Pontiac Solstice Forumany advise?
I've got a 2007 2.4L with an inoperative "air distribution" system. It is stuck blowing only through the dash-level vents. Can't get it to blow at foot level or defrost level. I've tested the control knob by verifying that pushing it turns on rear window defrost, and twisting it to the far right engages the A/C compressor. Seems it's commanding properly so I surmise the distribution actuator isn't responding.
I've looked through the factory service manual and can't identify the actuator. In the old days, this would be a vacuum powered motor but I don't know what's in the Sky. Can someone describe it to me? Or maybe where it is? A diagram would be awesome!
