I checked the blend door and all is well and is working as it should. I was driving down the road and the a/c stopped working I quickly stopped and checked the compressor and it was not engaged. The pressures are good so what gives is it a pressure switch? Which one?

 

I am going through a similar issue on my 2002 it works when it wants i found out that my clutch somehow is offset not centered on the pully im hoping to clean it so all the clutches will engage if im correct, im hoping it will stop my problem
