Vehicle: XC90 2003 2.9 T6 Problem: A/C clutch doesn't engage. (initial thread: http://goo.gl/nU3WiL ) Got my CMM codes read today: CCM-001F air quality sensor: Signal too high CCM-0020 air quality sensor: Signal too low CCM-0004 compressor: Faulty signal Where are these sensors located?

I had my CCM codes read!

CCM-001F air quality sensor: Signal too high
CCM-0020 air quality sensor: Signal too low
CCM-0004 compressor: Faulty signal

Where are these sensors located?

Could the system be overcharged? Basically the 'gap' has to be as small possible without the clutch to grind on the pulley when it's not engaged. Given it doesn't engage at all, assuming there is correct pressure in the system, I'd try getting an evaporator sensor from another car and swap it see w...

Now that's a tight place. The S60 is quite a bit larger, still not easy to insert tabs. I actually cut and slide in some spark plug shims and bent them in place because once the plate rotates it will throw them right away. Just make sure the plate makes no noise or the clutch material will disappea...

UPDATE 1: So today I gave the stainless steel ties another try, jammed each of them through each side of the ring spring in such way that zip tie passes under the rubber thingy *see pictures below**. Managed to reduce the gap to a tight 0.4 and 0.5mm by moving the ties a little and later on, to a t...

I attempted the zip tie fix today and failed miserably. There is absolutely no way to reach it from the top and there is no access panel behind the wheel either. Hell, even measuring the gap was a challenge (had to build a primitive extension for my feeler gauge.) The compressor is surrounded by fra...

I'm thinking about going with stainless steel zip ties. Any thoughts?

I will attempt the zip tie fix in the following days. Can't see myself doing it from up top, hopefully the access panel will give me enough room to play with.

I think 0.6mm is too large. Got to be around 0.3mm. You may upload a picture to let us see I don't know how it goes on the XC90 but on my S60 here's how the job looks like https://www.youtube.com/watch?v=KAGDkwYSFY4 There also a quick fix http://forums.swedespeed.com/showthread.php?158177-I-ve-had-...

Hi, I checked the gap:
I used the 0.55mm and it slid right in, so I tried the biggest blade I had (0.63mm) and it wasn't even a tight fit. So I guess this is my problem?
