Hissing noise when I press AC button.
The other night i was at a stop sign and as i started
to proceed forward, i hear a pshhhhh noise and as i
proceed at 25 mph onto my street i hear gringing
like my brake pads would if they were bad but they
are not. The next day i turned my car on and
started to drive, there was no sound or anything
anymore. Then when i turned my vent on i hear a
low hum then when i pressed the AC button i hear
a clunk noise and then a continuous hissing sound
. I turned the button off and the sound went away...
i turn it back on and it clunks once and then hisses
t's only when the car is on. And even then, it's only
when I turn the A/C on. If I just use the vent, the
noise isn't there. But once I hit the button to turn
the A/C on, it starts up; hit the button to turn the
A/C off, the noise goes away. The noise is also
there when I turn on the defroster, but it goes away
when I turn off the defroster
