My 2003 Suburban developed a leak in the windshield washer system, either near or on the reseroir. I have replaced the plastic container, only to still have the leak present. Very difficult to isolate as the drip is slow and water puddles on a flat spot on the tank. There are 2 electrical pumps (one to the front wiper, one to the back wiper?) in addition to a electrical float. Any known issues? Suggested repairs?

More than likely a pinhole in the hose, they cost a few bucks at the auto parts store

I had the same issue with my 03 suburban. One of the pump housings was cracked. A new pump and housing was about $80 so I put some epoxy on the crack. That was over a year ago and I have not had any more problems with it leaking.
