Buyer's checklist
What to check before buying a used window regulator
- Distinguish between power and manual regulators, and confirm motor wire connector pin counts (e.g., 2-pin basic vs 6-pin express auto-up/down with anti-pinch).
- Inspect regulator cables for fraying, rusting, or derailment from plastic pulleys, and check scissor gear teeth for stripping or binding.
- Check glass attachment clips or mounting clamps to ensure plastic snap tabs aren't brittle or broken.
- Verify front door vs rear door and left vs right side specific mounting hole patterns, as regulators are non-interchangeable across doors.
