Why is my AC squealing when front AC is on?

Asked by Dog326 May 22, 2020 at 10:14 PM about the 1997 GMC Yukon SLT

Question type: Maintenance & Repair

I have a 1997 GMC Yukon that squeals when
the front AC is on. When just the back AC is
on it is fine and quiet but as soon as I turn on
the front it squeals. Could anyone help me
diagnose what it is?

Is the noise inside the car or under the hood? Maybe the serpentine belt is squealing.
