I have a 1990 525i with a Seiko-Seiki A/C Compressor SS-811PB4 12V, BMW part# 64 52 1 386 948. It is a single groove compressor that used r-12 and It has Seized UP on me. It is getting HOT in Charlotte so I am getting desperate. Anyone know where I can find one or if there is another compressor that is compatible (I will switch to R-134 if necessary). Thanks for any help you can give.
I might be able to help. Give me a call when you get a chance. 1-866-799-3984. Ask for Rob.
