A/C Clutch doesn't engage

So my a/c clutch doesn't engage when I turn my a/c on. I checked the fuses, replaced the relay, jumpered the low pressure switch, and tried just filling the refrigerant to build pressure to get the clutch to turn on. I'm kinda stuck with what to try next or to look for so any help would be greatly appreciated. The jeep is a 1998 Cherokee 4.0 5 speed.

Do you have 12V to the clutch when the pressure switch is jumpered? If so, then you have a clutch issue. Check the air gap and adjust as needed. If that fails, replace the clutch (or compressor).
