AC cut out relay or switch when accelerating? 850 1994

My 1994 855 is still making a resonating noise with the AC on and driving at 65 MPH or when acclerating and the RPM reaches 2,800. If I turn the AC off during the resonating or buzzing the noise stops. If I idle the car in park with the AC on at 2,800 RPM there is no buzzing. The noise comes from the drivers side and the car has the manual AC controls.

Is there a cut out switch or relay that stops the AC when acclerating and if so, where would this switch or relay be located?

My Haynes manual does not show what the relays are in the fuse box.

Thanks for any help
