Default Chirping/belt sound in dashboard when hitting gas pedal
 

This is a weird one, starting hearing a sound which appears to be coming from the dash on driver side, its sounded like a the fan belt at 1st. I was driving today and the sound happens when I touch the gas pedal, its like a chirping sound, only will hear it when you hit the gas pedal.

Sounds to me like a vacuum leak, probably the brake booster.

I second the vacuum leak. I believe the booster is the only thing vacuum up there.
