Where labor overlaps, inspect the connector terminals behind any failed switch — heat damage there will kill the new part too.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2021 Kia FORTE5 was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2021 Kia FORTE5?
