Rain water
I know on these S class cars you can have rain water get in and mess up the ac blower, and other stuff.. I have been trying to be good about cleaning my cowl area.. I can see the vent on the right side is clean, but I do see a couple leaves below the starter battery.. Someone on here said the water can get in from under the starter battery, is that the case? Bottom line is, where should I be checking to make sure this doesn't happen to me? I had a heavy rain lastnight and I noticed I have a little chirp from my AC blower when it rains or I wash the car.. well I am replacing the blower today but I don't want it to happen again.
Thanks
PS Even with the heavy rain the car inside is bone dry.. yet the blower is obviously affected..

Well I just replaced the blower and I think this was just from time and age.. The rain lastnight was the worst we've had in years and it was dry as a bone in the blower, but it was rusted horribly and hard to turn, vs the new one which was easy.. plus everything around it was dry as a bone. I replaced it with a new one and all is well now.

Also FYI guys threads in this board have made it sound like the hvac blower is a horrible job, but it's just about the easiest thing you could do. 10min max. 5min max for filters. If I were you guys I would pull your blowers and put a couple drops of oil on the bearing seeing as these cars are prone to moisture in that area.

I was thinking, while it was dry inside the blower after a huge rain I would still like to know exactly where the water supposedly gets in so I can keep it clean. Does anyone know exactly where the spots to keep clean are? Is there really a spot under the starter battery? Thanks

Simply make sure cowl & L/R drains are kept clear. For your reading pleasure - 221 if VIN is 0335381 or below (as of 030660 additional sealing pads, 033539 new drain grommets put into production) http://workshop-manuals.com/mercedes...a/c_operation/ + next pages.

Thanks but what I am asking is where are the l and r drains, the little plastic drains by the hinges of the hood? What about under the starter batt. etc, thats where I was told a drain was too.
