Cargo Window Construction on the CS-Platform Pacifica
Replacing the stationary cargo quarter windows on the original 2004–2008 Pacifica requires working around deep interior trim and integrated alignment hardware unique to this body style. These side glass panels—referenced in the NAGS catalog as DQ10356 for the driver side and DQ10357 for the passenger side—are fixed directly into the rear pillar aperture rather than sitting in a movable channel. Factory units shipped under Mopar base numbers 05116345AA/AB on the left and 05116344AA/AB on the right.
Every original cargo window on this crossover came standard with dark solar privacy tint across the Base, Touring, and Limited lines. The glass itself is solid tempered safety glass bonded to a factory-moulded black polyurethane perimeter reveal. Instead of depending entirely on external tape to hold position, the frame uses dedicated mechanical locating studs and retaining nuts (such as Mopar hardware 6506601AA) passing through the sheet metal. These studs index the glass cleanly between the rear door shut-face, the roof rail stamping, and the lower rear quarter sheet metal.
Interior Surroundings, Radio Grids, and Leak Sources
Gaining clear access to the window requires stripping back the upper C-pillar trim, the D-pillar garnish mouldings, and the wide lower rear cargo trim panels. Because the mechanical indexing fasteners sit behind these interior walls, the panels must come off to unthread the retaining hardware and disconnect any embedded glass connections. On models equipped with the upgraded factory audio packages, the cargo window glass also houses the diversity AM/FM antenna grid; if the terminal clip or fine surface lines snap, radio signal reception drops immediately.
I handle these replacements entirely through a mobile setup, travelling directly to your driveway or workplace parking spot anywhere in Toronto and across the GTA. Addressing issues on this vehicle often traces back to aging perimeter mouldings. Over years of sun exposure, the encapsulated outer polyurethane trim tends to dry out, shrink, and pull away at the edges. When water breaches that weathered rubber or slips through gaps in dried factory sealant, the runoff bypasses the pinchweld entirely and gathers down inside the spare tire storage tub beneath the cargo deck floor.
Does this quarter glass include a rear defroster or wiper?
No. The rear quarter glass panels on this model do not incorporate heating wires or wiper arms. The electric rear window defroster and rear wiper assembly are housed strictly on the liftgate window at the back of the vehicle.
Can the perimeter rubber moulding be replaced without replacing the glass?
The outer reveal moulding is bonded directly to the tempered glass as a single encapsulated piece during factory production. If the outer rubber is cracked, degraded by UV rays, or pulling away from the paint, the entire glass assembly must be replaced to restore a clean, weathertight seal.
Why is there water pooling beneath the rear cargo floorboards?
Water collecting in the lower spare tire well or storage compartment is a common symptom of a failed quarter glass seal on this vehicle. Rain seeping past damaged exterior encapsulation or degraded original bonding tracks down behind the plastic C-pillar and D-pillar panels, pooling at the lowest point of the trunk floor.
