I'm not a mechanic, but I'm just now learning basics because I'm in dire need to sell my car because I'm broke. It all started 3 weeks ago. The air went our and under the hood was making awful grinding noises. I took it to my grandad and he listened with a stick and determined it was the compressor. He didn't think it was worth fixing. A few days later it started to squeel I opened the hood and seen metal shavingshavings under the compressor. I reved it up to 5 rpms and it started to spark. Later that night I got it home and the belt locked up and I couldn't get it back on. I P ayed 255 for a drive belt, reman compressor, and a dryer and Payed someone 150$ to install it. I took the keys with me to work by accident and he couldn't test it after he installed it. I got home and cranked it up and the transmission and engine was jumping really fast and really hard. I finally got it cranked and it's still blowing out hot air. Fuses were blown put new ones In and still not working. And just checked and the same jumping snapped my new motor mount

 

sounds like either the power steering bearing or alternator bearing is bad

with the belts off, try spinning them and see which one has roughness

if they are good then it's likely one of the tensioner bearing is bad

 

That could be a reason for not getting cool air?

 

we don't know if the mechanic did the ac work correctly at this point
