Moveable Glass and Hardware
Moveable Glass and Hardware
This domain covers door glass, window regulators, run channels, and hardware adjustment. You must understand how to remove and install glass, adjust regulators (power and manual), and align glass to the roof rail and weatherstrip. Traps include misadjusting the glass causing wind noise or water leaks, forgetting to lubricate moving parts, and damaging defroster grids or antenna wires when working near glass. Also, be aware of side impact airbags in seats or doors; disarm them before removing door panels. Worked example: A power window that moves slowly may have a binding regulator or worn motor; check for obstructions in the run channel and lubricate with silicone spray. Rule of thumb: Adjust glass so it contacts the weatherstrip evenly with slight pressure; typically, the glass should be flush with the roof rail. Key concepts: window regulator types, glass adjustment, run channels, weatherstrip alignment, airbag safety, lubrication.
