I have this exact problem on a 1987 300e, how bad a job is it to replace the outside/fresh air accuator, and where is it?

You lucky rascal, you. Be on the lookout for the rest to fail though. The one that controls outside air coming in to the cabin can make you think the air conditioner compressor ain't working. It won't shut off that 100 degree outside air and the system can't overcome it. Good luck!!
