So, I made the jump and purchased a 1983 300D yesterday. It's in great shape but the A/C blew out a couple weeks ago. It still blows, it just blows hot. Any suggestions? I heard that I might have to change out the seals and everything IF there's R12 in there. I'm not sure about that yet, but i'll update if I figure it out.

Also, in an unrelated note... Does anyone know what the far-left switch on the center console does? It looks like it turns on a light, but nothing changes when I turn it on and the previous owner didn't know what it was either.


Thanks, and I'm happy to be in the owner's club.
