1997-2000 Dodge Avenger Deck Lid Panel: Cracking, Fading, and Replacement Guide
This essential guide covers the common cosmetic failures of the rear finish panel and its surprising interchangeability with the Mitsubishi Eclipse.
- This panel is directly interchangeable with the 1995-1999 Mitsubishi Eclipse coupe, expanding your used part options.
- Failure is cosmetic (cracking/fading); the part does not affect vehicle operation.
- When buying a used panel, carefully inspect for hairline cracks and ensure all rear mounting tabs are intact.
- Replacement is a very simple DIY job that takes less than an hour with basic tools.
Symptoms of a Failing Deck Lid Finish Panel
Failure of the deck lid finish panel on the 1997-2000 Dodge Avenger is almost always cosmetic. Due to its age and plastic construction, these panels are prone to deterioration from years of sun and weather exposure.
- Cracking and Brittleness: The most common failure is cracking. Over time, UV radiation makes the plastic brittle. Hairline cracks can form, often starting around the mounting points, lock cylinder, or emblem. In advanced stages, pieces can break off entirely.
- Fading and Discoloration: The original color, often a dark or red translucent plastic, can fade into a dull, chalky finish. The clear coat may also peel or delaminate, giving it a patchy and worn appearance.
- Water Leaks (Indirectly): While the panel itself is not a seal, degraded or improperly installed mounting hardware can create a path for water to enter the trunk lid and, eventually, the trunk itself. If you have water in your trunk, the mounting points for this panel are one of several areas to inspect.
Pro Tip: The 1995-2000 Dodge Avenger Coupe was built alongside the Mitsubishi Eclipse and Chrysler Sebring Coupe. Many parts, including this deck lid panel, are interchangeable between the Avenger and Eclipse coupe models. This significantly expands your options when searching for a good used replacement.
Buying a Used 1997-2000 Avenger Deck Lid Panel
Given the age of these vehicles, a used OEM panel is the most practical and often only choice. New OEM stock is likely depleted, and aftermarket support for this specific cosmetic part is virtually nonexistent. Here’s what to look for when buying used.
Physical Inspection Checklist:
- Check for Cracks: Carefully inspect the entire surface, especially around the screw holes and any openings for locks or emblems. Hold it up to the light to reveal small hairline cracks that may not be obvious at first glance.
- Examine the Mounting Tabs: Flip the panel over and ensure all mounting studs and plastic tabs are intact. These are critical for a secure, rattle-free installation. Broken tabs are a major red flag.
- Assess UV Damage: Look for consistent color and finish. Avoid panels that are heavily faded, chalky, or have a peeling clear coat, as they are likely brittle and won't last long.
- Confirm Compatibility: This panel fits 2-door coupe models only. It will not fit Sebring convertibles or sedans. Remember to include 1995-1999 Mitsubishi Eclipse coupes in your search for a compatible part.
Why Used OEM is Better
For a part like this, a good-condition used OEM panel is superior to a theoretical new aftermarket one. The original Mopar/Mitsubishi part was designed for a perfect fit and to match the vehicle's other trim exactly. You get the correct shape, color, and texture, which a cheap reproduction likely wouldn't replicate.
A Note on Trunk Water Leaks
Many owners of this generation of Avenger and Eclipse experience water in the trunk. While replacing the finish panel, it's a perfect time to address potential leak points. Common sources include:
- Spoiler Mounting Bolts: If your car has a spoiler, the gaskets under the mounting points are a frequent cause of leaks.
- Taillight Gaskets: The foam seals around the taillights can compress and degrade over time.
- Trunk Lid Seal: The main weatherstripping around the trunk opening can wear out, tear, or be improperly seated.
- Finish Panel Mounting Holes: Water can seep past the nuts that hold the finish panel on. Applying a small amount of silicone sealant around the studs during reinstallation can help prevent this.
Replacement Difficulty & Cost
- Difficulty Rating: 1/5 (Very Easy)
- Estimated Time: 0.5 Hours
- DIY Feasible: Yes, absolutely.
Replacing this panel is a straightforward job requiring basic hand tools. The process generally involves removing the carpeted liner from the inside of the trunk lid (usually held with plastic push-clips), unbolting a few 10mm nuts holding the panel on, disconnecting the trunk lock linkage, and then swapping the panel.
Warning: Be gentle when tightening the nuts on the replacement panel. The plastic studs are old and can be brittle. Overtightening can easily crack the panel or snap a mounting point.
Cost Breakdown
| Part Type | Estimated Cost |
|---|---|
| New OEM | $200+ (If found, likely discontinued) |
| New Aftermarket | Not Generally Available |
| Used OEM (Avenger or Eclipse) | $50 - $150 |
| Shop Labor | $50 - $100 |
Frequently Asked Questions (FAQ)
Will a deck lid panel from a Mitsubishi Eclipse really fit my Dodge Avenger?
Yes, for the coupe models from 1995-2000 (Avenger) and 1995-1999 (Eclipse), the main body shell is the same. The deck lid finish panel is a direct swap between these two vehicles, giving you more options at the salvage yard.
Can I repair a crack in my existing panel?
You can try, but results are often temporary. Plastic adhesives or epoxies can be used on the backside of the panel to reinforce a crack, but it will likely remain visible from the outside. For a clean look, replacement is the best option.
Is this panel causing the water leak in my trunk?
It's possible, but unlikely to be the sole cause. Water is more likely getting in through degraded gaskets for the spoiler, taillights, or the main trunk seal. When you replace the panel, it's a good idea to use a small amount of RTV silicone around the mounting studs as a preventative measure.
How do I remove the trunk liner to get to the bolts?
The interior trunk lid liner is typically held on by several plastic push-in clips. You can use a flathead screwdriver or a dedicated trim removal tool to gently pry the center pin out and then remove the entire clip. Be careful, as the clips can be brittle with age.
