Buying Electrical Switch & Relay Parts for a 2018 Ford C-Max

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 2.0L L4 ELECTRIC/GAS 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: Brake Light Switch and Ignition Starter Switch .

Frequently Asked Questions

How many electrical switch & relay parts fit the 2018 Ford C-Max?

Our catalog currently lists 108 electrical switch & relay parts for the 2018 Ford C-Max across 24 subcategories and 16 brands, covering the 2.0L L4 ELECTRIC/GAS engine. Each part is matched to the engine(s) it fits.

What are the signs of electrical switch & relay problems on a 2018 Ford C-Max?

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 2018 Ford C-Max 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 2018 Ford C-Max?

Every part on this page is matched to the 2.0L L4 ELECTRIC/GAS 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.
