Buying Electrical Switch & Relay Parts for a 2004 Cadillac SRX

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 3.6L V6 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: Headlamp Relay and Oil Pressure Sender / Switch .
