I paid $189 which included shipping from Gene Culley at GMParts.
He's always been fair on price and reliable. Like I said, I had a talk with him today and he said this part was the new version of the actuator and the only one available from GM now
JM, Like OP, I have read all posts known to man about this issue. bringing up old post, as I am one of the poor souls getting B0441, Outof range, drivers side. Tonight I REmoved and opened actuator(2001 Z06, manufactured in November of 2000, so may be old style) and all looks good. Good grease, no burned spots on circuit board. When replacing Fuse 27, I can hear left side blend door go through limits, but not drivers side. Drivers side Warm air condition occurs with and without AC on, so I am pretty sure it isn't R134 issue. heat on drivers side is same, AC on or off. Ideas?Glad that I could assist.
Stop right there. I posted a BIG ol' picture of the newer style actuator and gave a detailed description of the mechanical and physical differences of the older and newer actuator in THIS thread. So if you removed the driver's side actuator from your car, you should be able to CLEARLY identify which actuator you have. So my first question to you is, "Which actuator do you have?"...

No you are NOT sure it is not a R-134a issue because you haven't had the system evacuated in order to see exactly how much R-134a is in your system. You are guessing, which is what guys do when they want to spend a LOT of money trying to figure out what is wrong with their AC instead of performing a proper trouble-shooting procedure. I stress this big time in all the AC threads I post in. You have slightly gotten the cart before the horse by pulling the actuator. The first thing that you should have done is the evacuation procedure in order to see how much R-134 you have (which should be exactly 0.68 kg [1.50 lb] for your year car). By eliminating the R-134a as a possible issue, you can then concentrate on the other "most likely" issues that our AC systems experience.... When replacing Fuse 27, I can hear left side blend door go through limits, but not drivers side.

No patience required. I enjoy sharing information, although some of the thinner skinned guys always think that I am chewing their asses. I guess it is the Marine in me. I totally get you, brother. 1960's Submariner, 5 yrs 7 mos 27 days, but who's counting?
"The way the engineer's see it, you can drive a car in the summer time with no air but you CAN'T drive the car in the winter time with no heat (because the windows will need to be defogged). So low refrigerant always causes the car to default to heat."
I get that for failsafe to bilateral heat, AC on or off. But, not for driver's hot pax cool /cold regardless if AC on or off. So, that's why I'm stuck on actuator as root cause.
BTW, when I took it out, actuator was at midpoint, not at stop or "out of range" visually. It is new model with stops. watched it initialize, it went hard to to both stops, and rested at a stop. I then adjusted heat and watched rotator move. it takes a few secs then responds to heat or cool command, i.e., moves a little bit and stops. still showing b0441. I opened and shut blend door w wrench. it seemed stuck. Ima remount act'r and see if it will operate door now.
