2000 lesabre custom ac clutch dont engage.If ac relay jumped ac works great.Gauges show full charge.relay signal from computer not there.Relay good.My only guess is combo lo/hi pressure switch no good? Not giving correct signal to computer? Oil light on dash,display shows low oil pressure,but oil pressure ok! Could this prevent ac signal from going to relay?

checked ac charge with gauges-perfect.jumped out ac relay and ac works ice cold.either combo lo/hi pressure switch bad or low oil pressure seen by computer not allowing ac to go ready? I hope pcm ok.
