Hey I wanted to make a video about the 1998 to 2006 Chevy GMC pickups and as well as the 2000 to old six, the GM on full-size SUVs. About the blend or actuator. The heat actuator going out on the driver's side so when you like have a bad battery you have to get a boost or you change your battery or it just goes out on its own. Keto blow out on the driver's side only and nothing else. It won't switch to AC and everything else will blow out cool or hot whatever you choose. So the first thing I got deal was Google it and I got a few helpful hints on Google as to how to change this thing and it's a pain in the butt to get up in there. As you can see it's like behind the dash up under the dash panel and behind the center console but there's this little piece once you get the the guard off there's still this little piece right here that hangs down and if it weren't for that sucker you could get the blend or actuator out pretty easy. Tools I used was I used this flexible screwdriver which came in handy a lot. That actually helped me out a lot. I got that a few years ago I've been had it for years and on the end it accepts these little socket adapters and the size I used to get the splash guard off was it was a seven millimeter it's three seven millimeter screws and the one right in here right in here on this splash guard was actually really tough because it sits behind it sits up in there up in the behind the center console so I had to use this. I had to use this a combination of this and I got another seven thirty seconds one fit on there I'm sorry nine thirty second fit on there pretty good and though it was I was able to get out of that pretty quick with those tools but once you get to the actuator itself you have these small smaller seven thirty seconds bolts in there and these things are the first one is not that bad but the second one way up under the bottom right there is a pain in the butt to get to I mean I'm sorry as a pain I found another tool online I'll reference to I put the link to the tool on below that I think will be a little bit easier it's a little bit more expensive than this screwdriver head but if I ever have to do this again I'm probably on investing that tool just to have it lying around so I got that little boat out and I'm gonna go ahead and show the process of taking this thing out of there once you get the screws removed so basically you just have to kind of wiggle it straight down just pull it wiggle it straight down because it's on held in there by that little thing right here this right here is the the blend or knob that's what turns the blend or and that fits right into this groove right here so if you try to pull it straight back it won't work you have to pull it straight out of that and this little tab right here had like a little little bump right up it was hard to see on this camera maybe but this is what I did to repair this thing I don't want to say rebuild it but I did repair it excuse the sweat it's hot outside and it's longer than they call it spark but take these tabs it's got little click tabs on the sides like one two three four little click tabs you just pry those out with like a little small tool screwdriver whatever prime up and then once you get those pride up you can pull the cover off and I'll pull it straight out from this side the side with a label on it so like I was saying the label side and then you get those tabs it comes right off I wish I could show it on video but I don't think it have two hands no helmet cam right now but but I did was I tinkered around with it a little bit just to find out how it worked and what I learned was these gears working sequence with this motor and that's the first gear in the order that's the second one and that one link this small gear on this links up to this gear which links up to this one and the bottom half of this gear links with the gear on the control the knob that controls the actuator so what I learned was take this one off and just sit it aside and then I took this little last big gear out and if you flip it up under the bottom you'll see these little rings right here these little whatever you call these little points contacts these contacts actually come in contact with that black area down in there so all I got did was those the contacts were not protruding as far as I thought they should and they weren't even they weren't evenly touching I guess one of them might have been lifted off the rails and the other one was touching so they were making proper contact so I just bent them back a little bit back to make them further away from the gears and made sure they were both even spread equal distance apart and I also cleaned a little bit of the grease off this black area right here the black areas and stuck them down in there and tried to fit it in the car now and I did that I'm not trying to put it into the car I noticed that the doors were off this this part that goes into the blend door was actually off a little bit so I turned the blend door itself until I can feel that there was cool air coming out and made sure that you know I turned it one way it's hiding the other way it's cold it's cool once I did that I kind of like matched the cool side up to what corresponded to these lines on the back of the the label side of the blend or actuate a cover which was really this line right over here on the right side so I don't think I did it match those this up where there's a little I guess you can call a pointer notch in the in the actual sorry notch in the actual gear the main gear and turn it until on this right here I actually can you can turn this over and put it in the top part of the cover it's got two stops that'll stop you from going too far it only go that far or that far so I just put it in the top of the cover and I'll flip it over and make sure that it's pointing directly at that line with this gear it's pointing right at the line and then I just flip it back over and place this gear in its proper place or at least try to get it about where it needs to be and once I did that just flip the main side of the actually weight on top of it and it takes a little while to get it lined up but um once you get that lined up where everything will fall in place and the main part is getting this gear this gear right here back onto its shaft that's the main the main part of lining this up this part of state pretty much put but you have to get this gear back on that shaft right there try to do it holding the camera okay then flip it over and make sure you got this part has to be lined up with that first notch okay so I got it lined up it didn't take that long it just had to tinker around with it for a little bit but as you can see I got the lines pretty much pretty much right on in the middle of the notch now all I have to do is stick this back in and make sure my AC controls is all the way on cool now and then put this in the car before I make sure it's on cool before I turn it on then put this in the car and then test it and make sure it works so you already know how the installation process goes I'm gonna put the camera down and install this and then make sure it's blown out cool there one thing I don't have which I wish I had bought was the infrared thermometer that way I can point you know the thermometer at the vents to see how you so you can see how the temperature change so I might have to go invest in one of those so you can see this thing actually is working the same thing might work for you it might not but I hope it does if you you know want to get us a try that's why I'm making this video to help anybody that doesn't want to spend the time or the money going to buy their own actuator
