Buying Electrical Switch & Relay Parts for a 2021 Chevrolet Spark

On this vehicle, the switch and relay system covers the switches, relays and flashers that route power to everything the driver touches.

  • Confirm you have the 1.4L L4 engine — every part on this page is matched to it.
  • Read the notes on each row for position, trim and spec qualifiers before you order.
  • Where labor overlaps, inspect the connector terminals behind any failed switch — heat damage there will kill the new part too.
  • Cross-reference the manufacturer part number against your old part or a service-manual listing.

Start with the largest groups on this page: Oil Pressure Sender / Switch and Radiator Fan Relay .

Frequently Asked Questions

How many electrical switch & relay parts fit the 2021 Chevrolet Spark?

Our catalog currently lists 68 electrical switch & relay parts for the 2021 Chevrolet Spark across 30 subcategories and 11 brands, covering the 1.4L L4 engine. Each part is matched to the engine(s) it fits.

What are the signs of electrical switch & relay problems on a 2021 Chevrolet Spark?

Common symptoms include accessories that work intermittently, a click without action, or one function dead while its fuse tests fine. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

What should I replace at the same time?

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 Chevrolet Spark 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 Chevrolet Spark?

Every part on this page is matched to the 1.4L L4 engine. Then swap a suspect relay with an identical known-good one from the fuse box before buying — it is the fastest diagnostic there is. The notes column carries position and trim qualifiers where they apply.
