Hey Guys , I have a 300SDL '87 and I was trying to troubleshoot what my father was telling me about the issue he had when trying to fix the A/C....He said he went to recharge the system and when he did...he was putting the charge in on top and he said the charge was coming out of the bottom of the compressor as fast as he could put it into the top...I am pretty sure the compressor works and spins like it should...any ideas or expereince about what this could be?
