green brown puddle at corner of car

so found this greenish brown clear liquid on the ground, its coming out of the driver side front bumper. Looking from top there's some stain near the antilock break thing. car seems to drive fine, coolant is full.

What could this be? AC leaking? Coolant hose? Washer fluid leaking?

Wiper fluid leaking

Mystery solved me thinks. This looks like wiper fluid, and its leaking from the driver side front bumper, where the reservoir is.

So looks like either wiper fluid pump, grommet, both?

Replacing the wiper pump

Local store had the part so replaced the seal and.pump.

1) rubber seal definitly suspect. Wet side is gummy and sticky. Also the outlet tube seem flimsy and crocket, might be cracked

2) the oem replacement parts went on really loose and leaked initially. Took it off noticed its gritty, so flushed the reservoir and cleaned opening. mew parts still went on lose, but does not leak anymore.
