It broke? Or the compressor has siezed
Maybe the belt snapped and fell off. Are the pulleys shiny where it would have been?
I can spill the compressor with my hand .
Can you spin the compressor or the pulley?
Then its been taken off by a previous owner who thought it was expensive to run air conditioning.
I can spin the wheel on the compressor .
All of it or just the pulley? The pulley spins free until the clutch engages.
Can you turn the middle bit? Even just a little to check it's not seized.
Fit a belt, make sure there is gas and try it. Nothing to lose.
what happens if there is no gas
no air con!!
and it doesn't like being run if dry.........try it, if it works the great, if not then you'll need to dig deeper!
what happens if there is no gas
Nothing it won't engage if there is no gas pressure to close inhibit switch.
