tomdjoe Posted September 18, 2013 Report Share Posted September 18, 2013 Looks like I am having the blend door actuator issue. Driver side blows hot and passenger side blows as set on the digital control. I have looked but can not find the "how to" link for fixing the blend door. Does anyone have this information? Thanks in advance!! Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted September 18, 2013 Report Share Posted September 18, 2013 There really isnt a how to for it. The whole dash has to come out. Its a PITA. Shops normally charge between $800 to $1200 for the repair. Quote Link to comment Share on other sites More sharing options...
Grocery Getter Posted September 18, 2013 Report Share Posted September 18, 2013 Isn't there a way that it'll possibly reset itself if you pull the power for a few? The TBSSs are finicky at times with this issue. Some guys get away with a free fix. ALLDATA wouldn't have it? Good luck! Quote Link to comment Share on other sites More sharing options...
tomdjoe Posted September 18, 2013 Author Report Share Posted September 18, 2013 I read about the reset and I am going to try it. I hope it fixes it. Thanks Quote Link to comment Share on other sites More sharing options...
Muggs Posted September 18, 2013 Report Share Posted September 18, 2013 Under the hood pull the fuse hvac/icas in the black fuse box leave out a few mins and put it back in, start the truck and leave it alone it will run a recycle for the system sometimes this will fix it, it's worth a try and if it don't fix gonna have to replace the actuator most likely.

synyster_SS Posted September 19, 2013 Report Share Posted September 19, 2013 There are 3 blend door actuators for the automatic HVAC controls, if I recall correctly. I had your same exact issue with my 05 SS shortly after I bought it, the passenger side would blow as set on the control but the driver side would blow hot no matter what. Resetting the actuators with a Tech 2 scan tool worked 2-3 times, until the actuator gave out for good. I work at a GM dealership; with Service Information, I was able to figure out which blend door controlled what.. the one you need to replace is between the floor and the dash right behind the center console. You can replace it without pulling the console, although you need the hands of a small child. Lol. There are three 7mm screws holding on the trim piece under the dash behind the console, remove the trim piece and the actuator is right there. I did mine in a driveway at 10pm at night by the light of a flashlight.. no need to take it to a dealership to replace it, all you will need is the actuator (they are all the same, I used one out of my wrecked 06 Sierra with manual HVAC), and a little bit of patience. Hope that helps! Quote Link to comment Share on other sites More sharing options...
kcsilveradoss Posted September 19, 2013 Report Share Posted September 19, 2013 I didn't read through all of this, but if you replace yourself DO NOT PLUG IT IN until you have it installed. Quote Link to comment Share on other sites More sharing options...

highvoltamps Posted October 10, 2013 Report Share Posted October 10, 2013 How much do you want for the actuators? Do you want all four? There's a recirculation, mode and two air temperature actuators. Also a blower control processor which could be your problem. Quote Link to comment Share on other sites More sharing options...
