What Does It Do?

The rubber seal fits between the window glass and lifter rail, helping cushion the glass and maintain a secure connection to the window lifting mechanism.

It also helps reduce vibration and rattling during window operation.

Why Does It Fail?

Common causes include:

• Rubber hardening with age
• Cracking or splitting
• Compression and loss of flexibility
• Repeated window movement
• Deterioration from moisture and temperature changes

When Should It Be Replaced?

Replace if the rubber is cracked, brittle, compressed or no longer holds the glass securely.

Inspection is recommended when repairing window regulators, removing door glass or restoring the door assembly.

Checks & Diagnosis

Inspect the window lifter rail, rubber seal and glass mounting area for wear or damage.

Ensure the replacement seal fits correctly and the window moves smoothly without excessive play or rattling.
