My 2000 Chevrolet Silverado 1500 does THIS (See the Video) whenever I turn on the Windshield Washer. The VOP (Video Original Poster) shows 'How To Do' this Windshield Washer Reservoir & Pump Repair on his 2003 Silverado. However, these instructions will apply to most GMT-800 Full Size Trucks and SUVs. I’m including images of ALL the Parts required for a Complete Replacement of all this stuff from Top To Bottom that I just purchased via Amazon:
Time Required:
With Complete Prep and Post Time Testing? 45-60 Minutes
Tools Required:
3/8” Drive Ratchet and an Assortment of Metric Sockets and Drive Extensions
10mm Box End (Off-Set Wrench is Handy) and/or in 3/8” Drive 10mm Socket
13mm & 15mm 3/8” Drive Sockets (Just In Case You NEED them).
8mm (5/16”) Box End or Battery Terminal Specific Ratcheting Tool
Plastic Fender Well Retainer Tools & Replacement Retainers
A Flashlight or a Head-Band Lamp
Having a Milwaukee M12 3/8" Drive Battery Powered Right Angle Ratchet SAVES TIME!

After Watching the VOP... A Word To The Wise…
NEVER Wear any Wedding Rings, Bracelets or Watches & Metal Bands around ANYTHING Electrical or when working on anything from a Ladder.
If your Wedding Band EVER gets caught on anything and you happen to FALL at the same time… you can lose Fingers (and Tendons) on the way DOWN.
