Hi everyone. I'm new on this forum. I have a 1986 560 SEL that I love very much, except the A/C is not working. A friend of mine, who also owns a 560SEL, tried a few things last weekend: he checked the freon level--it was low and he added R134, he made sure it didn't have any leaks and he made the compressor come on (jumped terminals on a relay, maybe?). However, no A/C. Then, he noticed the fan was not coming on. (Is this called the auxillary fan?) He did something to make the fan work and then the A/C blew cold, but stopped blowing cold as soon as the fan was shut off. So, could this be a relay or the fan switch or something else? He checked some fuses and said they were fine. I would appreciate any advice and thanks in advance.
