Chirping noise sounds like coming from passenger side dash

Driving at 15 mph and above it sounds like a chirping (baby chicks) noise is coming from dash area, sounds more like on passenger side. Sometimes very loud once in awhile disappears all together. Had a person ride with me unfortunately noise was not loud at the time and hard to hear and he said it sounded like two bearings rubbing together that was not lubed. Also when I depress gas pedal when taking off I can hear a flutter then it disappears. These are not normal noises for this truck. Did not have A/C or heater on nor radio during these noises. A/C was worked on last year, do not use as it is too much for engine and clutch was just replaced.
