I am not sure which it is but I cannot turn the pulley by hand. How do you tell if the pulley is bad or the whole compressor? I went out to start the truck and it wouldn't start. It died so I restarted it and then I seen the smoke from the front of the truck. I opened the hood and the flipping belt was just hanging there. Is there a way to just bypass the unit for now? I wont be needing the AC till summer and that is several months away. Thanks in advance!

 

If the A/C compressor is not turned on it should be just riding on the bearing. My guess is that your bearing locked up. Buy a new clutch kit and replace. I don't think your compressor is locked up. Does the center part of the compressor spin by hand with the truck off?

 

You can buy an accessory belt for"non-AC" truck (at any automotive store),that bypasses the AC ,and you can drive without AC .

Good luck,

 

check the owners manual or look along the front by the radiator somewhere. there is usually a sticker with EPA info and a drawing for the a/c or non a/c belt routing.
