a/c compressor problem
just got a new r4 compressor (again) and i think it may have locked up. the only thing i can think of is maybe too much refrigerant. will too much refrigerant cause it to lock up? it was cooling very nicely the past 5 days, and then it locked up. should i get another compressor? would another brand perform better than an r4?
thanks

My compressor almost siezed when I used the wrong oil for the R134 refregirant. When I drained the oil from the compressor it was VERY thick! I flushed the whole thing twice and removed ALL residues from all the lines, evaporator and condenser, then I flushed the compressor very well with the correct oil, now everything seems to work very nice for almost 2 weeks on a daily driven vette.
If you have the correct oil and dont seem thick, then I think you have to remove the compressor, flush the whole thing, then put a new compressor back.

If the fitting on the back of the compressor is cold, then you have too much.
Pressures vary at temps and different systems etc. shoot for low 30's
After 5 days, chances are you had an oiling problem.

i don't know if the compressor was bad or not. it was brand new, not remaned.
but with like 50 psi it cooled nicely in my climate, it didn't freeze up or anything...

Thats exactly what happened to me when I had the wrong oil with R134 refregirant. I stopped and dismantel the system just before my compressor was completely siezed, luckily I had no permenant damage to the compressor. check my post in the auto a/c forum and I am sure you'll be able to fix the problem :
