Default weird sound coming out of a/c vent

so theres this weird sound coming out of the middle a/c vents. it comes from time to time but only when i turn on the car. the sound (if it comes on) starts even when i just turn the ignition but with the engine off i dont see any difference in performance its just annoying because sometimes it can be louder than my radio. and the sound is like a weird clicking noise combined with a high squeal any ideas?

I get a similar noise in my Grand Am.... I traced it back to a combination of the blower and the connection of the center vent..... I kick the blower to shut it up and pound the dash a little for the vent.... good luck.

Determine if it happens only when the blower on. If that's the case it's probably your blower motor. They will start to squeal with age. Also determine if it only happens with the ac blowing and not the heat.
