Replacing Door Glass on a 2006-2017 International ProStar
If you drive a 2006-2017 International ProStar, you already know it is a reliable heavy-duty workhorse. But dealing with a shattered or jammed door window while hauling freight across Canada is an absolute headache. You cannot just tape up a commercial truck window and expect it to hold up against highway winds, snow, or freezing rain. Getting that glass replaced right the first time is the only way to get back on the road safely and comfortably.
The Mechanics of ProStar Door Windows
Here in the shop, we pull apart ProStar doors on a weekly basis. The 2006 to 2017 models share a very specific door structure. The door glass itself is heavy, and the window regulators take a massive beating from constant road vibration and daily use. When a side window shatters, thousands of glass shards drop straight into the bottom of the door cavity. They get packed into the tracks, plug up the water drain holes, and mess with the motor gears.
Common Failures We See on the Road
Before we even touch the new glass, we look at why the old one failed or what secondary damage happened when it broke. Here is what usually goes wrong:
- Regulator strain: The heavy commercial glass puts a lot of pressure on the lifting mechanism, wearing out the internal cables over time.
- Track misalignment: If the glass shifts even a fraction of an inch off its track, it binds up and refuses to roll smoothly.
- Worn weather seals: Harsh Canadian winters destroy exterior rubber seals, letting water inside the door and freezing the glass directly to the frame.
How We Handle the Replacement Process
When we swap out the passenger or driver side door glass on these International rigs, we never cut corners. First, we carefully remove the interior door trim. These panels use plastic retaining clips that get extremely brittle in cold weather. We use dedicated pry tools so nothing snaps or cracks during the teardown.
Next comes the cleanup. We vacuum every single piece of broken glass out of the door shell. If a technician skips this step, those leftover shards will grind against your new window or jam the regulator the next time you roll it down at a weigh station.
Final Fit and Testing
Once the door is clean, we slide the new OEM-quality door glass into the tracks and bolt it securely to the regulator carriage. We run the window up and down several times, adjusting the tension so it seats perfectly into the upper weatherstripping. A tight seal is exactly what you need to keep out the loud highway noise and the cold drafts.
