Customer Question

Clutch on a/c won't engage, can't find low pressure switch on this vehicle to check it. Without eliminating this possible I can't start testing the control module on the dash.

Customer: 175 new compressor and or face and dryer. Vacuumed and filled clutch won't come on
JA: What is the model/year of your Buick?
Customer: 1998 regal 3800 on turbo
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: I can jump the relay and the compressor clutch engaged.
JA: Anything else you think the mechanic should know?
