2004 Impy. Last week a hissing started in/under the dash, right about the center of it from underneath. Lucky me, at the same time the A/C went from "not so good" to "not at all." Its not there when the blower motor is off. It sounds like a good ole' vacuum leak.
I havent snooped around yet, but arent the A/C/heat controlled electronically & not by vacuum? I may be wrong so thats why I'm asking. Dont say its snakes I need to take a look at it this weekend, just like to know what I'm looking for.

Well, I pretty much took the whole dash apart & fired it up to look around. Hissing was still there with the blower motor unplugged & the fan on After a little head scratching I wound up in the center of the dash. Its the A/C evaporator core. ouch! Thats not going to get changed until the day it needs a heater core & hopefully not by me Feel pretty stupid now for taking so long to figure it out, live & learn.
