Buying Electrical Switch & Relay Parts for a 2019 Ram 2500

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

Match the engine first. Every electrical switch & relay part here is engine-specific; each row shows which engine(s) it fits.
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: Power Window Switch and Door Lock Switch .

Frequently Asked Questions

How many electrical switch & relay parts fit the 2019 Ram 2500?

Our catalog currently lists 126 electrical switch & relay parts for the 2019 Ram 2500 across 37 subcategories and 16 brands, covering all 3 engine options (5.7L V8, 6.4L V8 and 6.7L L6 DIESEL Turbocharged). Each part is matched to the engine(s) it fits.

Do electrical switch & relay parts differ between 2019 Ram 2500 engines?

Yes. Every electrical switch & relay part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.

What are the signs of electrical switch & relay problems on a 2019 Ram 2500?

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 2019 Ram 2500 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 2019 Ram 2500?

First match the engine — each row shows which engine(s) the part fits. 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.
