The compressor spins, but if I spin it by hand (without the belt) there is almost no resistance. Same with spinning the clutch by hand - it spins freely. On subsequent tests, I couldn't get the clutch to engage even if I applied voltage directly.

I installed a new compressor this afternoon. The clutch still isn't activating normally, but it will if I apply 12v to the trigger wire. With the compressor engaged, I get cold air like I should. Next up is to check the low pressure switch.
