A worn sunroof seal is easy to ignore until it starts looking rough around the glass. On an older GMC Yukon, years of sun, heat, cold, car washes, and weather exposure can leave the rubber around the sunroof looking flattened, brittle, or uneven.
That does not mean every sunroof problem is caused by the weatherstrip, but if the seal is visibly damaged, checking it is a sensible place to start.
What Should You Look for Around the Sunroof?
Inspect the rubber seal around the edge of the sunroof glass with the roof closed. Look for obvious cracking, hardened sections, gaps, torn areas, or portions that no longer sit evenly against the glass.
It is also worth checking whether dirt or debris has built up around the seal. A weatherstrip can look worn when part of the issue is simply contamination around the contact surface.
Don't Assume the Seal Causes Every Water Leak
If you notice water around the headliner after rain, the sunroof seal is only one area to inspect. Sunroof systems may also use drainage channels and drain tubes to manage water that reaches the roof opening.
That means replacing the rubber weatherstrip should not automatically be treated as a cure for every leak. Before ordering a part, inspect the condition of the seal and consider checking the surrounding sunroof drainage system as well.
Check Part Number 22815954 Before Ordering
This replacement sunroof glass seal is listed under manufacturer part number 22815954, with 15837594 and 22891488 shown as interchange numbers. The Champoo Selected listing covers several GM vehicles, including the 2007–2017 GMC Yukon and Chevrolet Tahoe, along with selected Yukon XL, Escalade, Suburban, Silverado, Sierra, and Avalanche model years.
Because the fitment range includes multiple models and configurations, compare the year, model, existing seal, and part number before purchasing.
When Replacement Is Worth Considering
If the original weatherstrip is cracked, badly hardened, torn, or no longer sitting correctly around the glass, replacement may be worth considering. This listing includes one rubber sunroof glass seal intended for the upper sunroof area.
Before installation, clean the surrounding area and compare the replacement carefully with the original seal. If the sunroof has additional problems such as drainage issues, glass alignment concerns, or mechanical faults, those should be diagnosed separately rather than assuming the weatherstrip is responsible.
