1993-1997 Dodge Intrepid Rear Door Glass: A Guide to Replacement and Common Regulator Issues

Part Identification: Rear Door Glass vs. Rear Windshield

It is critical to understand that this guide covers the rear driver's side door glass (the movable window in the rear door), not the large, fixed rear windshield (also called a backlite). The part number DD09241GTY specifically refers to the Driver's side Door glass with a standard Green TinY finish. These parts are side-specific and cannot be interchanged between the driver's and passenger's sides.

Symptoms of Failure

While glass failure is usually obvious, related components can cause symptoms that might be confusing. Here’s what to look for:

• Visible Breakage or Shattering: This is the most common failure, typically caused by an impact from road debris, an accident, or a break-in.
• Spontaneous Shattering: In rare cases, tempered glass can shatter without any apparent impact. This can be caused by a small, unnoticed chip on the edge of the glass or internal stresses from manufacturing.
• Window Falls Into the Door: If you hear a loud pop or grinding noise followed by the window glass sliding down into the door, the window regulator has failed, not necessarily the glass. This is a very common issue on this vehicle platform.
• Slow, Sticking, or Noisy Operation: Grinding, clicking, or chattering sounds when you use the window switch point to a failing window regulator or motor. The glass may move slowly, crookedly, or get stuck.
• Deep Scratches: Scratches on the glass can impair visibility and weaken its structural integrity, making it more susceptible to breaking.

Known Issues, TSBs, and Recalls for 1993-1997 Dodge Intrepid

Widespread Window Regulator Failure

The first-generation Chrysler LH platform cars, including the Dodge Intrepid, are well-known for premature window regulator failure. The plastic and cable components inside the regulator assembly become brittle over time and break, causing the window to become inoperable or fall into the door. In some cases, the lift plates that attach the glass to the regulator can bend or break, causing the glass to tilt and bind. This is a more common repair than replacing the glass itself.

Recalls and Technical Service Bulletins (TSBs)

A search of the National Highway Traffic Safety Administration (NHTSA) database shows no recalls or TSBs specifically for the rear door glass on 1993-1997 Dodge Intrepid models. Existing recalls for this vehicle pertain to other issues like seat belts and engine components.

Buying a Used Rear Door Glass: What to Check

For a non-wear item like glass, a used OEM part is an excellent, cost-effective choice. It guarantees a perfect fit and tint match, unlike some aftermarket options. Here is a detailed checklist for inspecting a used door glass before you buy:

• Confirm the Correct Side: The rear driver's side (left) and passenger's side (right) glass are different shapes and are not interchangeable. Double-check that you are buying the correct one for your needs.
• Inspect All Edges for Chips: This is the most critical inspection step. Carefully run your finger along the entire perimeter of the glass. Any small chip, nick, or 'flea bite' is a stress point that can cause the entire window to shatter during installation or later from road vibrations. Reject any glass that is not perfect on the edges.
• Check for Scratches: Hold the glass up to a light source and look for deep scratches that you can feel with your fingernail. Minor surface scuffs are often acceptable, but deep scratches can compromise the glass's strength and affect visibility.
• Verify the Tint: Most OEM glass has a slight tint. The NAGS code 'GTY' indicates a standard factory Green Tint. Compare the used piece to your vehicle's other windows to ensure it matches.
• Inspect the Mounting Brackets: Check the points where the window regulator attaches to the glass. These are often plastic or metal pieces bonded to the glass. Ensure they are not cracked, broken, or separating from the glass.

Replacement Overview & Difficulty

• Installation Difficulty: 2 out of 5 (Easy to Moderate)
• Estimated Time: 1 - 1.5 hours
• DIY Feasible: Yes, this is a common DIY repair.

Replacing the rear door glass is a straightforward process that requires basic hand tools. The most difficult part is often carefully removing the interior door panel without breaking any clips.

Basic Steps:

1. Disconnect the negative battery terminal.
2. Remove the interior door panel by locating and removing several Phillips head screws and then carefully prying the panel away from the door frame.
3. Disconnect the electrical connectors for the window switch and courtesy light.
4. Carefully peel back the plastic weather barrier to gain access inside the door.
5. If the old glass is still in place, lower the window to align the mounting bolts with the access holes in the door's inner structure. Loosen the 10mm nuts that hold the glass to the regulator.
6. Carefully tilt the glass and lift it out of the top of the door frame.
7. If the glass was shattered, use a shop vacuum to thoroughly clean all glass fragments from the inside of the door cavity and the regulator tracks. This is crucial to prevent rattles and damage to the new glass.
8. Installation is the reverse of removal. Carefully lower the new glass into the door, attach it to the regulator, and test its operation before reinstalling the door panel.
