There are possibly two relays. One might be in the relay box under the hood, behind the battery. I know there is also one inside what is called the Alarm and Relay Control Module.
The horn relay for the 1999 Isuzu Rodeo is typically located in the fuse box, which is found under the dashboard on the driver's side.

If you're having trouble locating it, consulting the owner's manual can provide additional guidance.

On my 1998 rodeo the fog lamp relay is under the hood, on the passenger side mounted in a box that should have a label for all the relays and fuses under the lid.

If the headlights on a 2000 Isuzu Rodeo won't turn off, it could be due to a faulty headlight switch, a malfunctioning relay, or an issue with the automatic headlight sensor if equipped. Additionally, a stuck or damaged door switch can prevent the headlights from turning off when the vehicle is turned off. Inspecting these components can help identify the cause of the problem. If the issue persists, consulting a professional mechanic is advisable.
