* Under the hood in the fuse box: This is the most common location for relays in many vehicles. Check your owner's manual (if you have it) for a fuse box diagram showing relay locations. The diagram should label the fog light relay or specify its function.
* Inside the passenger compartment fuse box: Some vehicles place certain relays inside the cabin fuse box, although this is less common for exterior lighting. Again, check your owner's manual.
* Behind a panel in the dash: It's possible, though less probable, that the relay is located behind a panel in the dashboard. This is usually only done for relays linked to more sophisticated systems.
To find it, you'll need to:
1. Consult your owner's manual: This is the most reliable source. Look for a fuse box diagram or a section on relays.
2. Check both fuse boxes: Carefully examine both the under-hood and (if present) the interior fuse boxes. Look for relays that are labeled or might correspond to fog lights based on their size and position.
3. Use online forums: Search online automotive forums specifically for Cadillac Catera owners. Mention the year of your Catera, as this will greatly improve the chances of someone having encountered the same question and providing an accurate answer.
Without the year of your Catera, it's impossible to give a more precise location.
