Bad ac compresssor?

[Yoter91]

Just bought an 80 and drove it home 1000 miles. Had no issues other than ac stopped working half way thru. Old me would have just replaced every potential part it could be but this time im trying to make sure I have it narrowed down correctly.

AC compressor wont engage. I used a jumper on the pressure switch to see if it would come on and got nothing. Then I hooked 12v directly to the compressor and still nothing. Just got my set of manifold guages delivered and its reading a static pressure of 100psi which seems to be in the acceptable range. Safe to diagnose this as bad compressor? Anything I could have missed pls do tell me.

Thanks

Sounds like you have electric clutch failure or the air gap adjustment is incorrect. Gauges will tell you nothing without the compressor running other than you do have some refrigerant. Suggest you download the factory service manual from the Resources section of the forum.
It's also more cost effective to replace the entire compressor than just buying the clutch.

Make sure the switch on the HVAC unit in the rig is actually working. My button would not stay engaged and the AC would kick off.
