OE 84820-0D140 — Power Window Switch for Hyundai / Kia

A supersession happens when the maker revises a power window switch and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 84820-0D140 we list the current reference; ask our desk for written confirmation before a large order.

KingMay supplies OEM-grade aftermarket parts built to the 84820-0D140 factory specification: material grade, dimensional tolerance and surface finish follow the original tooling. They are not dealer-boxed genuine parts, and we quote them that way so there is no ambiguity at customs.

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

Incoming batches pass a dimensional check, a material look-up against the electrical & sensors specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest electrical & sensors reference and narrow by build year. Send photos and we will cross-check the number for you.
