Some ideas, although I have a gut reaction for ya.

If the problem is no forced air then it's probably the blower motor. You can sorta check out the rest of the system by setting either max or min temperature and driving at interstate speeds (75mph here in Colorado) and setting the system to blow. If you feel warm/cool air as appropriate being naturally forced through the system by the air intake then the rest of the system is doing what it should but the blower is dead.

If the problem is no air, then the blower motor is probably dead. Did you get any chirping from the passenger's footwell for the past few weeks? Replacing the blower motor in the 560SEL is a real treat let me tell you. This is from the school of been there and done that, although it is easier than my 300CD.

Easiest way is to set the passengers seat in the most reclined and pushed back position possible. Then you'll be working upside down basically holding onto the headrest with your ankles. Once you have the cover removed, the motor is held in by an assembly tha uses 3 screws. Now the joy is goign to be removing the fan to place on the new motor or if you wanted to pay the extra $100 then you're new motor will have the fan pre-attached. Unless you have a dremel, epoxy, wrapping wire, and an overbearing drive to make things difficult, get the motor with the fan!

The rest is basically straightforward, but a little tedious... Not a difficult job, but it will take you the better part of a day if you've not much of a DIYer. I'm sure there's more comprehensive instructions running around, but if you get stuck I'm sure someone around here, including me, will be happy to help further.

I do not envy you the neck and back ache you'll get from this. I suggest ibuprofin or a beer!


Good Luck!
