Having problems with your 2000 GMC Sierra ?

I have a 1999 GMC Sierra with a plugged drain hole causing water to leak onto the front right floorboard. Where's the drain located?

Here is link to your HAVC system to your Sierra and #22 is where your A/C drain hose is located on the fire wall, passenger side. Find the hose to make sure there is no dirt that has clogged up the tube. \012
