Thanks, Jim. I'll look for your post tomorrow.

I stay away from most shops in Macon except Deaton. They are all notoriously rotten, especially when it comes to MB and diesels.

I'm also going to try a new auxiliary fan relay switch. I noticed that the fan doesn't come on, even when the compressor's on and the engine temp is 90+. That may be part of the problem, as well.

Jackson MB redid the compressor and the drier three years ago. It hasn't worked right since. When I picked it up from them and told them it didn't seem very cold, the tech actually said to me, "Well, you can't expect much. This is a very old car." Arrgghh!

Thanks for all of your help.
