C230 Water leak

I noticed I have water leaking from the front left wheel well, right at the front tire guard. Its clear, clean water that is coming down. It has been doing it for a few days now, and I'm not entirely sure what it is. I thought it might just be the window washer leaking, but I'd be shocked if it held that much water (and water still comes out on the windshield). Any thoughts or ideas?

Have you been running the A/C lately? It's likely just condensation from the evaporator coil.

I've been getting a small puddle of water frequently coming from near the passenger's side tire, even on very dry days. I thought maybe it was coolant but after looking at it closely and sopping some up with a paper towel, it was definitely water. I don't use the air conditioner so I ruled out water from the AC.

Anyway I finally figured out where it was coming from. In the channel at the bottom of the windshield by the wipers, there are 4 weep holes that drain away water from the windshield. I poured some water in there and saw that 2 of the holes worked fine, but the other 2 were clogged. I used a foot long piece of weed whacker cord to fish down in there to open them. No more leak.

I think what was happening is that the water was slowly seeping through the clogs and out through the tubes that connected to those weep holes. My parking spot is under an oak tree so I'm guessing it got clogged with pollen.
