CHANNEL SUB-ASSY, BACK DOOR GLASS

Rear Back Door Glass Channel Guide ️

This rear window channel is the U-shaped guide that holds and centers the tailgate glass. It keeps the pane moving straight, seals out water and dust, and stops rattles on rough roads. A healthy channel protects the glass, the regulator, and the interior trim.

How It Works

The channel presses into the tailgate frame and forms a smooth track with flocked lining. As you raise or lower the back glass, the lining reduces friction, cushions the edges, and keeps perfect alignment. It also supports the seal line, helping drainage and cutting wind noise.

Why You Need It

Off-road and daily use wear the lining. When worn, glass can scrape metal, slow down, or jam. Moisture and grit then reach the regulator and motor.

If It’s Damaged

• Glass rattles, squeaks, or tilts
• Scratches or streaks on the pane
• Slow or uneven window travel
• Water leaks, tailgate rust, motor strain

Tech Tips ✅

• Replace in pairs if both sides track the glass
• Seat fully; use approved weatherstrip adhesive where required
• Clean channels and apply silicone-safe dry lube
• Relearn or adjust regulator after install
