Yeah, secondhand mondeo. I like the car,  but a couple of late summer storms rapidly made me hate the leaking sunroof. Far out Ford, worse designs may exist, but it feels like you worked hard on this one. 

The clue was here:

But really, I know now that the stupid non return value probably needs to be drilled out. Who runs half inch water tubes through a 3mm non return value and barb, straight into a 90 degree bend? This sort of stupidity ought to be compensated for with easy access for cleaning, right? Nope. Drop the glove box, and the fuse board, clip the cable ties of various bits of loom, pull out the insulation material. Then you can start work on the press fit rubber fitting that passses through the sheet metal, into the wheel well. 

I still like the car. Just not as much.
