Help please!! No a/c
 

Hi,
PLEASE! I need some help. My daughter has a 93 Regal with only 61000 miles on it. The a/c is not working. I checked for voltage at the plug on the compressor and it's zero. I swapped the relays under the hood back and forth and got nothing. I checked for voltage where the a/c relay plugs in and there is no voltage there either. When I turn on the a/c inside the vehicle, the clutch on the compressor doesn't engage at all. Any suggestions on where else to look or what else to try? Thank you in advance for your help.:confused:
