Description
CRL FW393L Dual-Vent Window – RAM ProMaster Driver Side Middle and Rear Quarter 159" WB (2014-2026)
Rear quarter vents are the heat exit point in most ProMaster builds. Front and sliding door openings bring fresh air in, but a rear quarter dual-vent window is what lets warm air leave and keeps airflow moving across the cabin.
The CRL FW393L is a vehicle-specific dual-vent window designed for the driver side rear quarter panel of RAM ProMaster vans. It installs using a clamp ring mounting system for a secure, serviceable installation and a clean factory-style appearance.
