Thanks for posting this. Fixed mine today after watching this video. Dealership wanted $1200.00. Fixed it myself for about $5 for new solder.

I just did this today, too. I used some wire I had(did all three) instea of re-using the ribbon. So, six solder joints re-done later and I put it in. It worked. What a miracle. Thanks, for posting this. It gave me the knowledge and courage to try it. Also, the high replacement cost of the whole unit gave me I-have-nothing-to-lose courage.

Thank you for doing this video, it was very helpful. I was able to do a 2006 by just removing the center knob and leaving everything in place. Used a long fine tip soldering pencil, fine electronic solder, wearing a headlamp on my forehead and reading glasses. Worked through the small curved opening above the wires. Used a very small screw driver to carefully position the broken end of wire over the solder pad on the board and then quickly applied a small ball of solder to the pad and wire, was able to get each of the 3 wires first try. The center wire was still connected but re-soldered it anyway. You do need a steady hand and the right iron and solder. May not be the best method for everyone but it can be done and only takes a few minutes.

My Aunt wants me to thank you for posting this . she was told the repair would be $450.00
i told her i would look into it for her as i am the family's go to repair person .
this was the first video i came upon and you were right on !! All 3 wires were broken .
after taking some time i was able to fix it . biggest issue was clearing the holes so the wire would go back thru.
From both of us thanks for the Info/Video !!

I just completed this repair just as you describe! It was easy except for stripping and re-soldering the short gray ribbon cable. That was difficult at my age! Thank you so much for your very helpful video, sir!!

DIY Brian you This fixed my AC problem. Easy fix once the issue is diagnosed. Thanks for the video!

just fixed the same problem on my 01 highlander. Removing and installing is a job anyone can do, but had my brother in law do the soldering as he has experience in that area . the cost of a new unit from my local dealer is $1400, so well worth doing it yourself.

Brian you have saved people so much money with this video. Thank you. First time doing precision soldering, this took my quite a while to get it right with how fragile the wires were in my veichle . But eventually got it fixed. Cost me about $50 for soldering iron, multi meter, and refrigerant.

Just fixed the temperature control in my highlander using your video. Thanks Bri 🤙🏼

Been dealing with this issue for 15 years lol...but honestly this should have been a recall...THANK YOU!

[MikeinTexas]

Hi thanks for your guidance. Fixed it as instructed and it worked. Only thing I couldn't do is the soldering. So I google electronic repair shops. Had to pay 40.00 to have them fix thanks and as easy as you showed. Took them just a few minutes to repair.

i have the same problem with my 2005 highlander, now I know to fix it thnks  for the video very 

[lensmaticoptical]

Thank you Brian. I tried to solder 1st time in my life and it worked. I mess up with wire lock clip while pulling up and break it (might be very old). I use hot glue to hold wire in the clip board and it work well. Best way is open the clear plastic at the back and release wire at the top side. Now both heat and AC are working perfectly.

My Toyota dealer wanted $1500 to fix my intermittent climate control on my 2006 Highlander. I followed the instructions on this video (my ribbon cable was broken in two places, just like in the video) and in less than two hours I fixed the problem. Thank you DIY BRI!!

[mitchbergren]

Thank you so much! Been struggling with min not working for a couple years and the dealer wanted 1200 bucks!

[kimhumphrey]

First, thanks! Your diagnosis was spot on. Kept turning from hot to cold arbitrarily. Took 30 min to take apart as your steps were exactly right. The ribbon was broken just as suspected. Since I don’t have the tool to remove the solder easily I just stripped the wires and soldered them to the stubs on top. Worked perfect. This saved major expense. Even refurbished controls are not cheap and the new control unit is like $1200. You wouldn’t realize it’s something this simple if you had not posted this video. Thanks

I have the same problem with my 2004 Highlander and have been putting off having it fixed because the dealer wanted almost $1000K to fix it (most of it was for the aftermarket part.) My Highlander has 340, 000 miles on it (yes, that's right, and still runs perfectly.) But I clearly don't want to put a grand into it for this. But it is getting colder and with this video I am confident I can do this myself. This was very instructive and I'll let you know how it turns out! Thank you.

[bryanmchenry]

Thank you so much for this video! Like most that have commented, I had a friend help me with the soldering. But everything else was very easy to do. I saved $1200 because of this video!

[josepheasey]

Perfect video, this was exactly our issue. We didn’t have any extra wire or a desoldering tool and the soldering iron was not great but we got it back together at $0.

[jimthumerzs]

This is the best video I've seen to address this issue.

I've found as a temporary measure, you can sometimes move the control all the way to hot/cold a few times and it will then work where you set it.

If you're like me and feel confident in your ability to remove the unit from the car, but don't think you could pull off the soldering, there are online businesses that will repair the unit and ship it back to you for under $100. Be warned that some of them say they won't work on yours if you've already attempted the repair yourself.
