W123 water leak / sway bar bushings

[Johnhef]

I am still trying to track down my water leak problem.

Planned on playing with it a little tonight but the sway bushings took too long. Basically after a run through the carwash or when its rained overnight, with the first 90 degree left turn i make, it dumps a lot of water onto the blower motor from inside the heater box. My blower motor is apparently not a big fan of this. I had to replace it the other night after it locked up and started cooking.

I have covered most of the usual problem areas, under the battery tray has been sealed 2 years ago, still holding -no leaks there. The hood spring cavities have been clean and drain as they're supposed to. The left and right side vent/cowl drains work as they're supposed to and the heater box drain doesn't appear to be clogged so I'm at a loss. Where the hell is the water coming from and why doesn't it drain out of the box on its own?

I don't believe its my sunroof drains ( I think I've checked these before) but I'll test them tomorrow night.

What I did end up doing tonight was replacing my sway bar bushings. The old ones were trashed, almost an inch of play with the bar. The right side was easy to replace- remove the battery tray and easy access to it. The left side was a bit harder. I suppose it could be made much easier by removing the brake booster, but I didn't have enough time to do all that tonight. I was able to access the top nut from inside the wheelwell and the lower nut from above the brake booster. I greased up the bar and slid the new bushing in from near the oil filter housing, it was a tight squeeze getting it behind the booster but I managed to make it work. Steering did feel a little tighter on the drive home, but I thought I'd mention it incase anybody was thinking of doing the same.
