2007-2010 Ford Explorer Sport Trac 'Breezeway' Back Glass Regulator: Diagnosis & Replacement

Vehicle Fitment Warning: Explorer vs. Explorer Sport Trac

Symptoms of a Failing Back Glass Regulator

When the rear 'Breezeway' window regulator begins to fail, you'll likely notice one or more of the following symptoms. Because the regulator is a mechanical part, failures often start with noises or unusual movement before a complete breakdown.

• Grinding, Clicking, or Popping Noises: This is the most common sign of failure. These sounds often indicate a frayed or snapping cable, or broken plastic guide pieces within the regulator assembly.
• Slow or Jerky Window Movement: If the window struggles to move up or down, or moves in a stuttering motion, it can point to increased friction in the mechanism, a failing motor struggling to move a damaged regulator, or stretched cables.
• Window is Stuck or Unresponsive: The window may refuse to move at all when you press the switch. While this can be the regulator, it's important to first rule out simpler electrical issues.
• Glass Drops or Won't Stay Up: A completely failed regulator may no longer be able to support the weight of the glass, causing the window to drop down into the rear cab wall.
• Crooked or Misaligned Glass: If the glass appears tilted as it moves, it suggests a broken guide or a detached lift point on one side of the regulator.

Diagnosing the Problem: Regulator, Motor, or Switch?

Before buying a replacement regulator, it's crucial to confirm it's the source of the problem. The issue could also be the switch, wiring, or the motor. Forum users report that diagnosis can be tricky.

1. Check Fuses and Relays: According to the owner's manual, the rear window may share a 5A fuse with the moonroof. If your moonroof works, the fuse is likely good. There is also a separate 20A relay for the rear window in the engine compartment power box that should be checked.
2. Listen for the Motor: Have a helper stand near the back of the cab while you operate the switch. If you hear a clicking from the relay and a humming or grinding from the motor, but the window doesn't move, the regulator is the most likely culprit.
3. No Sound at All: If there is no sound when you press the switch, the problem is more likely electrical—the switch itself, a bad ground connection, or a wiring issue.
4. Check for Jams: On the Sport Trac, the exterior weather stripping seal can become loose and fall, potentially jamming the window mechanism. Inspect the window track for any obstructions.

Buying a Used Back Glass Regulator

Since Ford has discontinued the new OEM regulator (7A2Z-7827008-A), buyers must turn to the used OEM or new aftermarket market. A quality used OEM part is often the best choice, offering original factory fitment and durability that can surpass cheaper aftermarket options.

What to Inspect on a Used Part:

• Cables: This is the most critical inspection point. Look for any signs of fraying, kinks, or rust on the steel cables. Run your fingers along them (carefully) to feel for any broken strands. A damaged cable is a guaranteed future failure.
• Plastic Guides: Check all plastic components, especially the clips that attach to the window glass and the pulleys the cable runs on. Look for cracks, stress marks (white discoloration), or any signs of breakage.
• Main Assembly: Ensure the main metal track is not bent or twisted. Check for any signs of heavy corrosion that could impede movement.
• Verify the Part Number: If possible, confirm the part is a genuine Ford 7A2Z-7827008-A. While other parts may look similar, only the correct one will fit and function properly in the Sport Trac's unique rear window assembly.

Cost of Replacement

Pricing can vary based on your location and the source of the part. Since new OEM parts are discontinued, the comparison is between aftermarket and used OEM.

Replacement Overview

Replacing the rear window regulator is a moderately difficult job for a DIY mechanic. The process involves removing the rear interior trim panels of the cab to access the assembly.

• Difficulty: 3 out of 5
• Estimated Time: 2-3 hours
• DIY Feasible: Yes, for those comfortable with removing interior panels and drilling.

The original regulator is often secured with rivets that must be drilled out. The replacement can be installed using new rivets or, more commonly for DIY, with nuts and bolts. The motor must be unbolted from the old regulator and transferred to the new one. The glass must be carefully supported and detached from the regulator clips before removal.
