I'm talking about the drains on either side of the bottom of the windshield. Does anyone have a wonderful idea for roto-rooting those drains? I have a flexible grabber tool that I can shove down several inches, but it is hitting a solid clog of years old gunk.

I've also tried string trimmer line, but I can't force it past the clog.

I've tried an air hose, but it's almost impossible to get a good seal to be able to pressurize the drain line.

Am I correct that those lines should drain out behind the front wheels, about where the front fender seam next to the door is? Has anyone had any success going up from the bottom or pulling the drain line entirely?

On my 300E I am getting a lot of rainwater runoff down under the battery, etc. and I really would like to have those drains working!
