Heated Wiper Parks and NAGS Glass Numbers
Sorting out the right windshield for this minivan comes down to whether your van has heated wiper elements along the base of the glass and what year it rolled off the assembly line. Upper trim levels like the ES and SXT frequently came with the Cold Weather package, which added an electrical de-icer grid embedded in the lower ceramic frit line to melt frozen slush off the wiper blades. Base models and mid-range SE editions generally skipped this feature, relying on standard solar green glass.
Because Chrysler revised the glass shape and electrical leads after the early model runs, there are three primary aftermarket options tracked under the National Auto Glass Specifications (NAGS):
| NAGS Part Number | Model Years | Wiper De-Icer Grid | Glass Tint |
|---|---|---|---|
| DW01410 | 2001 | Yes (Embedded bottom grid) | Solar Green (GBN) |
| DW01411 | 2001–2004 | No | Solar Green (GBN) |
| DW01470 | 2002–2007 | No | Solar Green (GBN) |
All of these variants include a broad black ceramic frit band behind the rearview mirror that functions as a third sun visor, along with a factory-bonded interior rear-view mirror button. None of the windshields in this era contain forward-facing lane cameras, rain sensors, or heads-up display optics.
The Plastic Cowl and Corroded Wiper Pivots
Working on the lower edge of this glass requires completely clearing away the large two-piece plastic cowl screen. This panel spans the base of the windshield, housing the washer nozzles and directing rainwater into the cowl drainage trough. Over the years, road salt and moisture settle directly into the splines of the wiper posts. The tapered metal shafts seize hard to the wiper arm hubs, meaning I almost always have to use a mechanical puller tool to release the arms without damaging the delicate plastic screen or bending the wiper transmission linkage underneath.
The plastic cowl itself is notorious for broken mounting clips and dried-out rubber edge seals. When the clips loosen, the hard plastic taps against the lower edge of the windshield at highway speeds, creating an annoying vibration or buzzing sound in the cabin. The soft upper rubber weatherstrip also splits over time, letting rainwater bypass the cowl and pour over the back of the engine. When setting the new glass and finishing the exterior with a fresh 3/4-style reveal moulding (profile DM1226 / GGG 1226), ensuring that cowl sits flush against the bottom glass perimeter is essential to keep wind noise down.
Under-Cowl Linkages and Interior Pillar Trim
Whenever the wiper assembly is stripped down for glass work, the underlying wiper motor transmission linkages deserve a close look. On these minivans, the factory plastic linkage bushings get brittle with age and pop off their ball studs without warning, instantly killing wiper movement across the glass. Mechanics also pull this entire cowl assembly out whenever they need access to the rear spark plugs, coils, or heater core lines against the firewall, which often leaves the plastic cowl warped or missing fasteners by the time I see the vehicle.
Inside the cabin, the windshield is flanked by large plastic A-pillar interior garnish mouldings that seat tightly against the glass borders. I back every windshield I install with a one-year warranty on the glass alongside lifetime coverage on my workmanship, making sure the interior pillar trims seat securely into their factory retainers without rattles once the job is finished.
