Ok i bought the car with the AC not working. The thing in the front that kind of looks like a circle with a triangle in the inside wasnt installed before PO said when installed it would smoke. So i just left it off, and it still worked somewhat, not like ice cold (because i never tried it) but it did blow colder air. So fast forward to yesterday, I started my car and nothing was wrong. Then when i toook off, boom it started weird, loss power, and smoke and smell. So I checked and....... The pulley came about half way off and the belt came off the pulley and around the black circular part of the compressor. and the smoke and smell was coming from the belt rubbing against the compressor. So, my question, do i need to replace the whole compressor? or do i just replaced the bearing/clutch assembly? ill take pictures tomorrow if you want to see it.
