Changing the HVAC mode module on 2006 4Runner 

Thanks for posting this! I just did this on my son’s 04 GX470. The bottom right screw that goes from the servo case to bracket was tricky for me. I found that unscrewing the 2 accessible bracket screws first was important. That allowed me to pull the bracket up so I could access that bottom right screw. Also, I installed the white plastic “wheel” first, and then attached the servo motor. The key is to pay attention to the orientation of the wheel when you remove it. Even if you don’t though, it’s easy to see how the wheel will need to sit in relation to the half moon connector that is on the servo motor. I found that it was MUCH easier to attach that wheel to the 3 arms FIRST, then connect the servo motor to it. At first I connected the wheel to the servo, and it was very difficult to get the arms in the channels. At first I thought it would be a guessing game to figure out which “channel” each arm should go into. But if you look closely at it, it actually is evident which one each should go into. Thank you again, I wouldn’t have had the confidence to do this job without your vid!

Unscrewing that upper second screw on the bracket is probably the most frustrating thing i've ever attempted. Thanks for posting this btw.

The buzzing has been an intermittent problem for a couple years in my 03' 4Runner. It acts worse in the extreme heat of Arizona summer. For the most part the function was still there, it just buzzed intermittently. Then on a 100 degree day, I lost the ability to direct the AC to our faces and it was hot as hell. My wife was in the car and started talking about selling my precious (260k and going strong)! Hopped on RU-vid and found your video. Thanks! I've been trying to figure out how to change this part for two years. Nothing seemed reasonable to try at home. One video I watched drilled a hole in the AC duct work where the cabin filter sits in order to get the last screw. Your method is totally doable with patience and standard hand tools. Once unscrewed and disconnected, I found it easiest to bring the old module over the top of the bracket. Brought the new one in the same way. I got it all aligned in the white linkages before screwing it back in. Thanks!

Same issue on mine (05 SR5 4WD V8, 245k). Thank you for posting this!!!

I used a tie wire through top somewhere across the door tracking plate and tied it tight then used hot iron to burn a hole in cabin air cavity to access straight to the hidden screw. Once all screws are out then use flat screwdriver between motor and guide plate to pop it off the actuator shaft(wire holds plate in place during switch out. reverse procedure.

It control the hot air ?? The AC of my 4Runner 2006 work fine, super cool, but not hot air.

Great tips, thanks!

Do you happen to know the part number for the "one that controls the temperature"? Thank you.

I wonder if a flexible screwdriver shaft and a right angle adapter can get in there for that 3rd screw. Are you in NC? I see your Hatteras and Uwharrie videos. I've biked the Uwharrie mtb trails. I did an adventure race out there and we hiked some of the ORV trails. Would a slightly lifted t4r do ok on those trails?

In my 4 Runner the air works fine, it's just that there is no air passing through the cabin vents.

I'm working on this issue right now on my GX and it looks pretty much the same. I may have messed up and disconnected the yellow air bag connection and all other connections when disassembling. I heard that could be sketchy and maybe I needed to unplug battery prior? Do you have any thoughts on what to do now?

I had my mode door actuator replaced at a Pep Boys. The airflow is not the same, air leaks through the defroster and the floor vents. Any suggestions?

So does the wheel come out also? Or do you just leave it were it is and just pull the module out? Trying not to damage or get the arms in wrong position! thanks in advance!

Did you take out the blue cable before bending the bracket?

So my a/c works on the passenger side but there is a like a high pitched squeeling noise coming from the dash when the A/c is on... it does not work on my driver side... my mechanic told me the blend door actuator was located on the driver side... its not. There is nothing on the drive side at all... So now I am tryin to figure out what the hell to do... was your heat working or A/c and was it both sides that it worked on or just one? I need help please.

Is this part the same for air recirculating? Mine it’s open all time and it’s a pain in the a… because AC doesn’t work properly

Hello. Would this part also control the Recirculation mode? It doesnt matter if my Recirc button is On/Off, i still feel outside air coming through the vents. The Recirc button lights up, Fan is off, no AC running, and yet i still feel outside air coming through.

i have a 05 4runner single zone blows warm on drivers side and cold on passenger side anybody had this problem and did you resolve issue

Thanks for the video! I have the same issue, ordered the part, and am gonna install today or tomorrow. How do you know what the correct channel is for the three little arms? When messing around earlier I think they may have been repositioned and I wanna make sure they are in the correct channel before plugging in the replacement module.

Got the servo out of the bracket but now having trouble getting the wheel off the servo. I don't wanna break the little clip. Any suggestions? Great video btw.

instead of buying the entire 200 dollar module, is it possible to just buy the 35 dollar servo motor and put into the existing metal bracket?

Just recently had to change this piece on my 06 4Runner... Not an easy task...

What’s the part number? Thanks

Get rid of it, trade it in
