Question about Buick Rainier
If the fuse is good the next thing is to see if you have B+ at the AC switch. Then turn the switch on and make sure you have B+ out of the switch. Check for B+ with the switch on at the low pressure switch. Jump the switch if there is B+ and see if the voltage stays the same or if it drops as it should. If no change in voltage you have an open circuit or a bad relay between the low pressure switch and the compressor clutch.
Let me know if you need further assistance. Kindly rate my solution. Thanks. Kevin
