Our guide covers 11 model years for the GMC Sierra 1500 (2015–2025) but only 9 for the Infiniti QX50 (2015–2024), so the GMC Sierra 1500 data reflects a broader range of generations.
The Infiniti QX50 window regulator is interchangeable across 16 model years versus just 12 for the GMC Sierra 1500 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.

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.
