I am having the exact same issue in my '88 suburban. I tried to tighten the belt but the issue still remains. I do suspect its a belt issue, as once hot it does seem to not be as tight. The AC is not blowing very cold, and I put 80% of 5.25 lbs of R134A in it, with about 8-9 oz of oil. It is blowing cold, about 60 degrees on a 100 degree day, but that does not really cut it in this weather. Is that normal for an R4, or should I be getting closer to 40 degrees?
The evaporator does get cold but doesn't feel ice cold to me. I was wondering if you ever got the issue resolved with the belt or not? I was planning on replacing the compressor. The compressor makes a lot of noise when in gear, but is quieter at idle. The belt vibrates a hell of a lot though, and the performance of the air conditioning isn't very good.
