Dear All,
I have Honda Accord 2007 2.4 , The problem I am facing from AC of my accord is that usually the AC cutoff after sometime and when is compressor engage again there is a sound Woooooo and it happens every time after the compressor starts working... Cooling is Fine .. .Sometimes if i am driving long way i am not feeling that compressor is cutoff or no but if you switched off the car then you will hear a sound like WOOOOO WOOOOOOOOO even the engine is off.Its like pressure relase.

Please help me .Is there any valve which is not working correctly or something elase..

Waiting for helpful suggestions...

 

Sounds a tough over the net......which means I'm not really following the noise. Could be the pressures equalizing when the system is shut off.

I'd start with having the system pressures tested "am driving long way i am not feeling that compressor is cutoff". Unless it is still really hot where you are, on a long drive while the car is moving the compressor should be cycling.

 

Dear All,

I am really happy to fix this problem.I have taken my car to a Honda Repair in Riyadh, Saudi Arabia ,The electrician just replace the AC valve and clean the blower and other parts and fixed it . That annoying sound was due to AC valve. Thanks everyone for support.
