Hissing Noise
I have two hissing noises. One relating to the a/c, but one related to the steering. I'm just gonna post them both up here. First the a/c: After a drive where I am using the a/c, I shut the car off and get a hissing noise that can be heard inside coming from the passenger side and outside from the passenger side in area of the a/c condenser, but not sure if it is that. I don't hear anything while driving, and the air blows cool-cold. The hissing lasts for about a minute or 2, and only happens after the air was in use never when I use the windows. The steering: When I turn corners there is a slight hiss sometimes not all the time. If I am making a long turn it will hiss for a second or two, stop for a second or two, then start again :4-dontknow:
Thanks in advance for any input.

The a/c sounds like a minor leak. My suburban does that and needs o get filled twice a season. Havent been able to pinpoint it yet. The steering could do that at full turn, but check the fluid. If the fluids good, you might need a power steering pump in the future, but dont worry too much about it now. You will know when its time.

Thanks Southbronx for your input, the ac was the one I was a bit more worried about anyway because I live in south Florida and I need it. It doesn't seem too seriouse so I'll fill up the refrigerant and keep my eye out for a leak.

my '09 steering pump hisses at full turn, i believe it is fluid going through a bypass valve, see i ease up the turn just a hair & it goes away

Yea it hisses at full turn too, but it turns out that the fluid was just low for the power steering, I put fluid in and for the most part it has gone away. It was stupid of me not to think of that first. But as far as the air condition leak is there anyway to detect it without taking it to a shop? Or should I not worry too much about it, and just keep filling it up every once in a while until something bad really happens?
