The windshield washer reservoir tank in the Chevrolet Tahoe holds the washer fluid that is delivered through the spray nozzles onto the front and rear windshields and helps the wiper blades wash off dirt, grime and other obstructions. If the reservoir is cracked, dented or leaking, it may not be able to hold enough fluid to clean off the windshield. This dangerous situation can leave you practically blind driving through a rainstorm or blizzard. Fortunately, fixing a washer reservoir in the Chevrolet Tahoe is a rather straightforward task, although it may take you a couple of hours to complete.

Turn off the Tahoe and open the bonnet.
Remove the battery by removing the terminals and the mounting nut using the socket wrench. Lift out the mounting hardware and the battery. Take out the tray by removing the mounting bolts with the socket wrench. Doing this gives you access to a top bolt holding the windshield washer reservoir in place. Remove this bolt and place it in a different pile from the bolts for the battery and battery tray.
Kneel down beside your front wheel well and look for the clips holding the splash shield in place. Pry these clips off and tuck the splash shield behind the tire to reveal the windshield washer reservoir.
Turn on your flashlight and aim it beside the windshield washer reservoir, illuminating the mounting bolt somewhat deep in the cavity housing the reservoir. With the long extension remove this bolt.
Unplug the delivery hose and power cord from the windshield washer pump, which is attached to the side of the reservoir. Pull out the windshield washer reservoir.
Thoroughly clean and dry your windshield washer reservoir.
Open the plastic tank repair kit--which can be bought at any auto store--and take out the sandpaper. Use it to slightly sand the area around the crack that is causing the windshield washer to leak.
Rub the surface of the reservoir with degreasing alcohol and a cloth. Place the fibreglass sheet from the repair kit over the crack and coat it in the epoxy from the repair kit. Allow the epoxy to dry for about an hour and then reinstall the windshield washer, delivery hose and pump, spray shield and your battery tray and the battery itself.
