What would cause the ac compressor on an 87 YJ 258 cu in not to kick in without a boost from the battery first then it cycles fine?
My87yj
if the gap between the clutch plate on the front of the compressor is too wide it will also have a hard time engaging.
A/C clutch relay too weak to initiate current demand, clutch windings weak, poor ground or even inline diode (if equipped). When you jump start the compressor you are surging the wire windings which aligns the electrons (temporarily) so the next cycle requires less of a jolt.
