Hey Guys. I've got a 2005 E500 which is still under factory warranty. The problem i'm having is that it takes 1 to 3 minutes for the AC to kick on after you turn it on. This includes the fan also. We've taken it in to the dealership and of course they can't get it to delay. after we picked it from the dealership today it did it twice. You can put the controls on high fan and nothing happens and in about 1 to 3 minutes it kicks on and works just fine. Any ideas what the problem might be? I looked up previous records on the car and the previous owner(which is the service manager of Mercedes Benz of OKC) had the same issue with the car. and the mechanics notes say they couldn't find any codes or problems.

MB does have a bulletin on a/c blower operation for that & most 2005-07 cars.

MB bulletin number P-B-83.25/76c

File is too large to post here.. send me a e-mail if you want a copy.
