hissing noise
#4
List your specs and mileage, and try to explain the area that you hear the noise. For example, front right tire, engine, shifter and so on. Specifics for noises are nice, I would know....I get customers saying the car laughs when turning and I work at a Toyota dealership (there high on pcp!) lol. We would love to help you out .

I have a 2006 MT Shinka with around 14K. The hiss will last around 2 seconds and souds like pressure dumping. Seems to come from under the passenger side dash/floor area and is more frequent when the AC is running. I live outside Charlotte and have recently lost a pet snake...

Most likely it's the A/C's expansion valve. It's located in the car on the passenger side. Either it's going bad or you're getting low on refrigerant due to a slow leak.

I have only heard it when the car is running. I think the AC expansion valve sounds likely. I will have the dealer check it out the next time I see them. Thanks for the help!
