air rush through vents during acceleration

Post by nthnnxn »

02 V70 T5
Problem: Loud "air rush" noise comming through the vents, ONLY during acceleration. Noise will happen with OR without the Fan or A/C On... During harder acceleration the fan speed will blow harder...once acceleration is over and constant speed is maintained, the air speed returns to the correct fan speed setting.

Perhaps related??? I recently did the "Zip Tie" Clutch Gap repair to get te A/C to function properly. I am not sure what the gap is due to no filler gauge...but the A/C works great now!!

Really, I am just praying for an easy solution... AKA No Unicorn!

Thanks in advance for any help

I did the zip tie ac compressor clutch gap fix as well on my 02 XC, but didn't experience the problem you're describing, so that may be unrelated .
