Windshield wiper fluid is leaking behind glove box onto passenger floor. Removed the glove box and could feel the firewall matting was wet. Only happens when I'm driving.
It has not rained in weeks or car washed so that is not it.
Fluid level in the holding tank is dropping faster than normal.
Could not find any hose or tube that appeared wet or
damaged in engine bay. I am totally stumped.

Try and trace the lines. Not sure how it could leak inside to your floor mats as I think it's all on the exterior of the firewall. Firewall matting under the carpet can wick up fluid from the bottom.

The windshield washer fluid should not be entering the cabin, unless there is a leak where the windshield meets the firewall.

the hose from the pump connects via a plastic pipe on the trim tray by the windshield. Water entering that area, should drain behind the front wheels, not inside the cabin.
