Hello, I am new to the forum and a friend told me to come check it out. Me and my girl just recently bought a 2005 S2000 with about 33k miles and we love it so far. Today as we were driving around with the a/c on I keep hearing this whistling noise when the a/c cycles. It goes away but when the a/c cycles again, the whistle noise comes back. Is this normal for these cars? I tried searching but couldn't find the right answer. Any imput is appriciated. Thanks in advance.

 

Yeah, it pretty normal for the S2k. I get the same sound when I use my A/C.

 

check the a/c pressure probably low i hear this allot in cars at work
and most of the time the system is almost empty gust enough
pres to cool and the compressor constantly on/off

cool, thanks guys. I work at a Ford dealership so I'll check the a/c system when I go back to work and recharge it for the heck of it. I'll keep ya posted.

 

normal. it did the same on my 02 and my current 07.

on some REALLY humid days..you'll see a white vapor come out of the vents for a few seconds.

Had the noise on my 00 since day 1 I think. .. And the vapor really freaks you out the first time you see it
