It takes a minimum 12V to engage the clutch. The hotter it is, the more voltage it takes. Plus, when the clutch plate wears, it takes more juice to pull the clutch all of the way to the electromagnet.

I would check the clutch gap, it needs to be around .025 for optimal range. Usually at around .040, operation can become iffy.

If the compressor gets too hot, there is a thermal cutoff. Usually caused by a low charge.

IF you over charge the system, the evaporator can build up ice. Blowing 'cold' at 55F sounds nice to me.
