2013-2018 Ford C-Max Side Window Glass: Part Numbers, Tint, and Replacement
Your guide to identifying the correct replacement side glass for your C-Max hatchback and avoiding common installation problems.
- The most common reason for replacement is physical breakage; there are no known widespread defects causing spontaneous failure in this model.
- The OEM part numbers DM5Z-5825713-A, FM5Z-5825713-A, and GM5Z-5825713-A are all for the REAR LEFT (driver's side) door glass. Verify the correct part number for other positions.
- If your window is intact but won't move, the problem is the regulator, motor, or switch, not the glass.
- When buying used, the most critical inspection is for chips along the edges, as these can cause the new glass to shatter later.
Symptoms of Side Window Glass Failure
Unlike mechanical parts, the failure of side window glass is almost always visible and caused by external factors. There are no diagnostic codes or complex symptoms. Failure is straightforward.
- Complete Shattering: This is the most common failure, usually due to an impact from road debris, an accident, or theft. Tempered glass will break into many small pieces.
- Cracks: While less common for tempered side glass than for laminated windshields, a powerful, localized impact can cause a crack or a "bullseye" without shattering the entire pane. These cracks can compromise the glass's integrity.
- Scratches: Deep scratches from wear and tear, improper cleaning, or a worn window guide can obstruct vision and weaken the glass over time.
- Increased Wind Noise or Water Leaks: If you notice new wind noise or water intrusion, it could be a sign that the glass is no longer properly sealed or aligned within its track, which can sometimes happen after a poor installation.
Warning: While problems with the window not moving up or down are common, they are almost always caused by the window regulator, motor, or switch, not the glass itself. If your glass is intact but won't move, you likely need to diagnose the power window system.
Known Issues, Recalls, and TSBs
For the 2013-2018 Ford C-Max, there are no specific recalls or widespread Technical Service Bulletins (TSBs) related to the side window glass spontaneously shattering or failing. Most issues reported by owners are related to the power window mechanicals (regulator and motor) or electrical components (switches and fuses), which cause the window to become stuck or operate erratically. These issues do not pertain to the glass panel itself.
Identifying the Correct 2013-2018 C-Max Side Glass
Getting the right piece of glass is crucial. The Ford C-Max was only available as a 5-door hatchback in North America, which simplifies things. However, you still need to match the correct position (e.g., front driver side, rear passenger side). The OEM part numbers often supersede one another. For example, part number GM5Z-5825713-A replaces both DM5Z-5825713-A and FM5Z-5825713-A. Always verify the position before ordering.
| Position | Common OEM Part Numbers | Notes |
|---|---|---|
| Rear Left (Driver Side) | GM5Z-5825713-A, FM5Z-5825713-A, DM5Z-5825713-A | Standard solar tint. |
| Front Right (Passenger Side) | DD11965GTN (Aftermarket Example) | Verify OEM number with VIN for exact match. |
Pro Tip: The part numbers listed in the initial data (DM5Z-5825713-A, FM5Z-5825713-A, GM5Z-5825713-A) all refer to the Rear Left (Driver's Side) door glass. You will need different part numbers for the front doors or the passenger side. It is always best to confirm the exact part number needed for your vehicle's specific VIN and door position.
Buyer's Guide: What to Check Before Purchasing Used C-Max Glass
Buying a used OEM side window is a great way to save money. Since it's a simple, non-wear part, a good used one is often identical to a new one. Here’s what to inspect:
- Scratches and Pitting: Hold the glass up to a light source and inspect it from multiple angles. Look for deep scratches that you can feel with a fingernail. Minor surface scuffs are usually acceptable, but deep scratches can compromise the glass's strength and affect visibility.
- Edge Chips: Carefully run your finger along all four edges of the glass. Even a small chip or flake on the edge, where it will be hidden in the door frame, can become a stress point and cause the glass to crack or shatter later, especially with the shock of a closing door. Reject any glass with edge damage.
- Check for Hazing or Delamination: Although rare on single-pane tempered glass, check for any signs of fogging or film separation, which can sometimes be mistaken for a simple cleaning issue.
- Verify the Markings: Look for the manufacturer's stamp (often called a "bug") in one of the corners. It should say "Tempered" and include other information. Ensure it matches the markings on the other windows of your vehicle to confirm it has the correct solar tint.
- Mounting Points: The glass attaches to the window regulator with clamps or brackets. Ensure these areas on the glass are clean and free of any damage or leftover adhesive from the previous vehicle.
Replacement Overview & Difficulty
Replacing a side window is generally considered a moderately difficult task for a DIYer. It requires careful handling of the door panel and the new glass.
- Difficulty Rating: 3 out of 5
- Estimated Time: 1.5 - 2.5 hours
- DIY Feasible: Yes, for those comfortable with basic hand tools and removing interior panels.
General Steps:
- Remove the interior door panel. This involves finding and removing several screws (often hidden behind trim pieces) and carefully prying off the panel to release the plastic clips.
- Disconnect any electrical connectors for the window switch, speaker, or door lock.
- Carefully peel back the plastic vapor barrier to gain access to the inside of the door.
- If the old glass is shattered, thoroughly vacuum all glass fragments from inside the door and the window channels. This is critical, as a single leftover piece can shatter the new glass during installation.
- Unbolt the clamps that hold the glass to the window regulator.
- Carefully maneuver the old glass (or what's left of it) out of the door.
- Slide the new glass into the door and into the window channels, then secure it to the regulator clamps.
- Test the window's operation before reassembling the door to ensure it moves smoothly.
- Reassemble the door in the reverse order.
Cost Comparison: New vs. Used
The cost to replace a side window can vary significantly based on the source of the part and who performs the labor.
| Part Source | Estimated Cost | Notes |
|---|---|---|
| New OEM | $290 - $410 | Price for the part only, from a dealership. |
| New Aftermarket | $75 - $100 | From online retailers. Quality and tint may vary slightly from OEM. |
| Used OEM | $50 - $140 | A cost-effective way to get a genuine Ford part. Prices vary by salvage yard and condition. |
| Shop Labor | $100 - $200 | Typical cost for professional installation at an independent shop or glass specialist. |
Frequently Asked Questions (FAQ)
Is the front side glass the same as the rear side glass on a Ford C-Max?
No. The front and rear door windows are different shapes and sizes and have unique part numbers. You must purchase the glass for the specific door you are repairing.
My window is intact but it won't go up or down. Is the glass broken?
No. If the glass is not cracked or shattered, the problem is almost certainly with the power window system. The most common culprits are a bad window regulator (the mechanism that lifts the glass), the window motor, a faulty switch, or a blown fuse.
What tools do I need to replace the side window myself?
You will typically need a basic socket set (10mm is common), a screwdriver set (Phillips and flathead), a trim removal tool kit (to safely pry off the door panel without breaking clips), and a shop vacuum to clean up any broken glass.
Do I need to worry about different tints for the 2013-2018 C-Max?
The standard glass for the C-Max comes with a solar tint. While there aren't typically multiple factory tint levels for the side glass (like you might find with rear privacy glass on an SUV), it's always best to inspect a used part to ensure the tint level appears to match your other windows.
