Hissing AC

I have a '97 Subaru Impreza with aout 110,000 miles on it. Just tonight the AC started hissing from the glovebox as soon as I turn it on. I had this same issue about 4 years ago and it turned out the seal that connects the evaporator to the system was cracked. It was replaced and averything seemed okay, until tonight. Now it's winter here and the AC hasn't been used in several months. I turned it on to quickly clear some fog from the windsheild. Am I looking at another AC repair, or does this just need a recharge? I really only plan on having the car a couple more years tops... what does this noise mean? Prior to this the car sat for over a week in VERY cold weather without being driven... (New England). Any advice? Thanks in advance...

Before you panic, turn the blower up all the way for a few seconds and see if it clears a leaf out of the fan.

I was hoping that would be the case..... But it's not something in the fan, tried running it on high for awhile. It definately an air noise from the glovebox. The best I can do to describe the noice it if you had a can on compressed air and you were releasing it. I've read this could mean I need a recharge, of course if I'm low that means I have a leak. What is a better place to have it looked at, the dealer or an AC specialist (if they exist). Thanks in advance...

I have a similar hiss, though I call it more of a sigh, but for me it's when the heat is on. I get it when the variable temp dial is at around 2 o'clock.

Had it to the dealers (for an oil change and maintenance stuff) and while they acknowledge the issue - they checked everything they could short of pulling the dash and couldn't find the problem.... Said if I wanted to pursue that I'd have to schedule for a loaner while they yanked the dash and kept looking.

Since I seem to have one of the dash's that don't have interesting rattles, etc. I've decided to leave it be for the moment. It's somewhat annoying, but not anything critical.

BTW - this is an '02 WRX Wagon.

Mine is quite loud and only when the AC is on. I can easily hear it over the radio. I'm planning on waiting until the spring (and warmer weather) to get it checked. The car is a '97 with over 110k miles, so if it is a leak, doubt I'll be putting the money into it. Living in New England AC is a bonus, not a necessity......
