compressor problem
 

ok ..................if there is whining comming from your compressor is it dead?
the reason i asked is because my compressor was whining bad, so i got a used one and put it in but i did'nt fill it up right away, after driving it for two days it whined one morning so i took it out and got a shorter belt.
now does this mean the compressor is bad or this just happend because it was empty.
and if they are bad where are some places to get good compressors............................
