2004-2006 Chrysler Pacifica Roof Assembly: Sunroof Leaks, Damage, and Replacement Guide

Symptoms of a Faulty Roof Assembly

Failure of a roof assembly isn't like a mechanical part; it primarily involves physical damage, leaks, and related issues. The most common problems are almost always related to the integrated sunroof.

Water Leaks into the Cabin

By far the most frequent complaint is water leaking into the interior. This usually presents as dampness or stains on the headliner, often near the front A-pillars (the pillars on either side of the windshield) or around the sunroof opening itself. In many cases, the cause isn't a bad roof seal, but clogged sunroof drains. These small tubes are designed to channel water that gets past the sunroof seal down through the car's pillars and out to the ground. When they get clogged with leaves, dirt, or other debris, the water backs up and overflows the drain tray, seeping into the headliner and cabin.

Physical Damage

Obvious physical damage from hail, falling objects, or a collision is a clear sign of failure. Even seemingly minor dents on a roof can be difficult and expensive to repair correctly because they can stretch the metal. In a rollover accident, the roof structure can be compromised, requiring a complete replacement. There is also a rare possibility of the sunroof glass spontaneously shattering, though this is not a common event.

Sagging or Stained Headliner

A sagging headliner is often a direct result of a water leak. The moisture saturates the foam backing of the headliner fabric, causing the adhesive to fail and the material to separate from the underlying board. 🎬 See this step-by-step headliner repair guide Stains on the headliner are also a tell-tale sign of a past or present leak that needs to be addressed.

Rust and Corrosion

While less common on the main roof panel itself, rust can form around the sunroof opening or along the windshield frame where moisture can get trapped. This is a more serious issue that can compromise the vehicle's structure if left untreated.

Buying a Used 2004-2006 Pacifica Roof Assembly

For significant damage, replacing the entire roof panel with a used OEM assembly is often the most practical and cost-effective solution. Aftermarket roof panels are not typically available. Here’s what to look for when buying used.

Inspection Checklist for a Used Roof

• Verify Sunroof and Airbag Options: Confirm the donor vehicle had the correct options. Look for the sunroof opening and check the headliner or pillar trim for "SRS," "Airbag," or "Curtain Airbag" markings.
• Inspect for Damage: Carefully examine the entire surface for dents, dings, creases, or warping. Run your hand over the panel to feel for subtle imperfections. Even small dents can be costly to fix.
• Check for Rust: Pay close attention to the sunroof opening, the front and rear edges where it meets the glass, and the side channels. Any sign of bubbling paint or surface rust is a major red flag.
• Examine the Cut Points: A professional salvage yard will cut the roof at the A, B, and C pillars. Inspect these cuts to ensure they are clean and provide enough material for a body shop to properly weld the panel onto your vehicle. Avoid panels with jagged or poorly placed cuts.
• Sunroof Cassette and Glass: If the sunroof assembly (the "cassette") is included, check that the tracks are not cracked or broken and that the glass is free of chips and scratches.
• Headliner Condition: If the headliner is included, check for stains, sagging, or tears. A clean, intact headliner can save you hundreds of dollars in upholstery work.

Known Issues, Recalls, and TSBs

While there are no recalls specifically for the roof panel or sunroof assembly on the 2004-2006 Pacifica, there are some important related items to be aware of.

• Engine Cradle Rust: The 2004-2006 Pacifica is notorious for severe rust and corrosion of the engine cradle (subframe). While not part of the roof, it's a critical safety issue for any owner of this vehicle and something to be aware of during any major repair.

• Engine Stalling Recalls: Several recalls were issued for these model years related to engine stalling caused by software issues in the Powertrain Control Module or problems with the fuel pump module.
• Sunroof Drain Clogs: As mentioned, clogged sunroof drains are the most common source of water leaks. There are no specific TSBs for the 2004-2006 model, but the procedure to clean them is well-documented. It involves using a flexible wire or compressed air (at low pressure) to clear the drain tubes located in the corners of the sunroof opening.

Cost of Replacement

Replacing a roof panel is a labor-intensive job that should only be performed by a professional body shop.
