Ok, my light saying I was low on whindshield washer fluid came on so i went out and emptied a gallon of fluid into it. Well, two days later, i haden't even used the whindshield washer fluid and it says I'm low again. Has this happend to anyone else? My guess is that it'* leaking on the bottom somehow?!

Happens all the time. Tank cracks, or maybe gets a "wear-through" where it may have been vibrating against the body.

Beware, those tanks typically are expensive.

You might also check the gasket where the pump intake plugs into the tank.

Sounds like you done sprung a leak. Check around where the connectors plug in. Mine has three electrical harnesses on it.

check where the little hose plugs into the pump. mine came undone and wouldnt stay in there because the pressure of the fluid kept blowing it out. but a little superglue fixed that real quick.

I would never buy a washer bottle from GM junk yard time!!, I picked one up for $5
