All,

i need help...I have 2004 XC90 T5 with approx. 100,000 miles....the A/C blows hot air... Ive checked the pressure on the low side and it looks fine. I first noticed that the air did not cool on the passanger side (just blowing hot air)... then slowly the driver side A/C sarted blowing hot air... I also noticed that there was hissing sound coming from behind the glove compartment so I suspected that the expansion valve was acting up...

Any thoughts?

Those anyone know how to reach the expansion valve?

Thanks,

 

Are you 100% sure the freon level is ok?
You explained classic signs of low freon.

Just because there is pressure does not mean there is freon in there.
