Take it from me, it's not an easy job, but I did it.

I found so many things that were done WRONG on my car by 3 previous owners repair guys. The heater core was replaced around 2002, with the OEM replacement, but they didnt even put the heater box back together right, damaged vacuum lines, and had a sensor wire running across one of the defroster vent openings... I could look down in there thru the windshield and see the wire!

When I did mine, I got everything put back where it is supposed to be. There are no rattles and squeaks anymore, because I replaced ALL of the screws, and the missing ones were aquired at my local Benz junkyard.

Now, the heater, and all door flaps work correctly. No vacuum leaks anymore. Total time on the job: about 9 hours. Every time I run the heater now, I feel good.
