I posted a month ago about a problem I was having with my A/C. It would stop blowing (fan was roaring, but little air coming out) after about 30 minutes of drive time. Well, I have isolated the issue and it seems to be the condensor coil. The A/C runs constantly not cycling and the condensor freezes up not letting any air circulation through. It sounds like a thermo switch or something. I can turn off the A/C once it stops blowing and leave it off about 5/10 minutes and turn it back on and it works like it should.

Anyone have an idea of what part I need to replace.

 

are you getting any codes??? parts that you may need to replace could be a valve, a temp sensor or a clutch and pulley. Those are my suggestions not too good with A/C units engines are more my specialty

 

No codes....surprisingly it works like it should during heat of the day. It typically freezes up during my morning drive. As I mentioned, you can turn it off for 5 minutes once the air flow reduces and let the temp warm up; turn it back on and you are good to go.

 

try replacing the evap temp sensor. i believe xc90's have them.

I have the same issues... 2009 s40
Anyone in the Montreal area able to do this? I am not mechanically inclined and would be willing to pay! This is driving me nuts!!!

 

Anytime that I've had xc90 AC freezing up I've always replaced the condensers.
