Repair
- On 2007-2014 Tahoe, Suburban, Yukon and Escalade with moveable glass always replace the defroster tab (GM P/N 25916031) and the power connector (P/N 12034110); on all other vehicles reconnect the original defroster tab.
- Remove the rear defroster power connector and crimp a new one to the feed wire; the proper connector, P/N 12034110, is in the Packard Electrical Assortment, Tray 18, Position 5.
- Prepare the surface of the used defroster tab and the defroster buss bar with fine grain (500 grit) sandpaper or Emery cloth.
- Wipe the prepared contact area with Kent Automotive Acrysol (or equivalent) to remove residual oil or dirt.
- Heat the new connector on the buss bar surface to be soldered, holding the connector and defroster tab in place with long nose pliers.
