Video about fixing your Climate Control Unit (CCM) fan button. It will also show how to clean the cabin temperature sensor and fan. The car used is XC90, removing the CCM is slightly different on other models but the fix is the same.
Here is photo of the resistors you should resolder as well:

You can take the shift stick off … just pull hard up as the first
Great video! I can’t get the green tab off for the AC components. What tool where are you using in order to depress that green top and remove it?
Great tip! The solders on mine looked fine so I was sceptical that it would be that, saw that Kevin Crosby was also sceptical so I tried it and it now works perfectly again. If not for this video I would have bought a new pot. That would have fixed it too but with a lot more time for part shipping and effort with desoldering the old one and soldering the new one. Thanks!
My auto mechanic said it's the regulator or the blower or both so so you think it could be just this fix??
Did the soldering, now fan stuck at 100%, do you have any knowledge about what could be the issue?
Hello. You don't know what's wrong if you turn off the ignition, but the interior fan continues to work?
One more sub! If after almost 5 years can I fix one of the last pending I had, it will be a quick success!
Thank you. Works like magic
What temperature are you soldering at?
The knob on my 05 V70R stays at four, doesn’t go up or down, auto still works but will this fix this issue on the manual fan knob
Worked great for 15 minutes & then fan knob stopped working altogether again. 2nd time I resoldered the fan speed decreases by 1, then increases by 1 back & forth no matter which direction the knob is turned. Each click of the knob decreases then increases by 1. Any ideas if this is due to a connection issue on a resistor or 1 of the knob connections themselves?
Appreciate the video, that really helps. Question can i use regular soldering iron solder? I don't have the flux pen.
Super job! It worked on my 09 XC90.
Is that fan switch supposed to be able to turn around in complete nonstop rotations, with no stops?
THX for the DIY Video. I have the same problem on my 2008 XC90 and this will help me to fix my problem. You also talk about forgetting to resolder some SMT resistors. Could you please let me know or maybe you can edit your video and point with arrows what are the resistors you recommend to resolder too.
