ac accumulator/dryer needs to be replaced. on 2000 Chevrolet Blazer
I have a 2000 trailblazer that was leaking refrigerant at the clutch pressure cycling switch on the accumulator. Remove the switch and replace the "O" ring on the shaft. I also put a bead of RTV sealer at the switch base. No more leak!!
