A/C compressor clutch issues

[drewmgd]

Okay there was no sign all I did was turn my a/c off and then turned it back on and then there was nothing warm air. The clutch isnt engaging I have tried everything from checking the fuse which was good and using the paperclip trick nothing. Can anyone suggest what it could be? could the compressor just go out like that. Please help oh sorry its a 97 7.3 ps

Got a test light? See if you've got 12 volts at your paper clip. Then see if you've got 12 volts at the compressor. Then see if you got a good ground at the compressor (attach the test light to the pos post and check the other wire at the clutch). If you've got 12 volts and a good ground at the clutch, you need a clutch. I've found it's more beneficial to replace the entire compressor than try to fight the clutch on and off inside the truck - but then again, I've got the equipment to do that

i must disagree that the diagnostics should stop here. Use an ohm meter on the clutch if you get a reading under 200 ohms and no ac with power to clutch check the gap if wear has made this to large clutch will not engage. remove center bolt to pull off outer clutch plate and take out spacer washer reassemble and check gap. cool air should now be in the system. this worked for me on a 2001 f250 super duty 7.3l.
