I tried to search before posting and there is nothing on this anywhere on the web or here that I can find. 04; 5.4L EB ac is not working. I am a novice and do most work with the help of YouTube. So I have replaced the ac clutch and the relay, fuses. I have power at the high pressure switch but nothing at the comp clutch. It will not engage. When the only clutch went I foolishly self diagnosed with Google and added Freon to the system and it didn’t help. I removed a spacer from the clutch plate and that got it going. Well old parts go bad and the bearings on the pulley went out. So I’ve replaced the clutch and field coil but have no power at the clutch. I am troubleshooting one thing at a time and want to replace the pressure switches. I know where the high pressure switch is but have no clue where the low pressure switch is, and there is nothing on the web that is helpful, no parts on Amazon, Autozone, RockAuto, Advanced Auto have the same plug as the high pressure switch. Can someone please help me with location of the low pressure switch and maybe part numbers for both of them? Thanks in advance!
