Ac does not work, blower motor works, recently tried to convert from r12 to r134 no success, compressor does not seem to want to kick on as much as it should, also compressor seems to make a loud rattling sound when compressor does finally kick on. Any help will be appreciated -ian

 

Sounds like your compressor is bad.
