Default AC compressor not running

I have 12v at the compressor but it won’t engage. It there something else it needs besides the 12v? Inter lock or disable circuit? I can only see the 12v harness going to it. It there more?
Thx
Phil

If you have 12+ and ground at the compressor the coil in the clutch has failed. I have replaced several on these cars over the years. I have owned seven of these cars and still run three in my family.

I have looked into removing the clutch assembly on my L-Series car, but found it unworkable. The distance between the clutch and frame rail is too close to get tools in place to perform that work. I was unable to see any way of removing the clutch without disconnecting the compressor and removing it from the engine compartment. If one dismounted the compressor while keeping the lines connected it still means there is a significant problem to overcome to pull the clutch off of the compressor shaft. Additionally, when reinstalling the clutch one must re-gap the clutch surfaces, and they won't tolerate an inaccurate gapping. The clutch is engaged electromagnetically. A gap which is too wide or too narrow will result in improper operation of the clutch and therefore a compressor which won't work.
