2000 300M A/C Compressor Problem
Hello everybody, new member here with a problem I hope someone can help me with. I recently replaced the A/C compressor on my 2000 300m, (the old one locked up and shredded the belt).
The new one worked great for 10 days, then the belt started squealing and shredded that one as well, so I figured my new reman compressor was bad. However that evening while checking it out, it turned freely by hand.
I have now determined that when the engine is hot, a/c switch off (or engine not even running), and still no belt installed on the compressor, I am not able to turn the compressor by hand. After everything cools down it turns freely again.
Before I throw more money at it here are my questions,
Should I be able to turn the compressor by hand when the engine is hot? (I assume I should)
If the compressor was low on oil would it cause these symptoms?
In case it is normal not to be able to turn it by hand while hot, is it possible that a defective or improperly tensioned belt would cause it shred as it did?
Of course any other opinions or suggestions would be greatly appreciated.
Thanks for your time.

Thanks for the response. The compressor was supposed to be prefilled with oil, my mistake for not verifying. I assume that caused the failure.
New problem, after replacing the compressor again, now there is no power at the compressor. It does work by running a jumper from the battery. Relay and fuse is ok, what else do I check? Power wasn't an issue before the compressor failure.
Thanks again for any help you may provide.
