I had the A/C comressor pulley go out on my 94 fleetwood and i replaced it about a month ago but needed a special tool to get the clutch plate back on. finally found the tool at local autoparts store and put the clutch plate on. Now my AC does not blow cold. Also just yesterday i started hearing a grinding noise similar to when the pulley went out the first time. Is it time for me to replace the compressor? How hard of job would it be a for a non-pro.
