Where is the headlight relay located on my 90 XJ? Was out and ran over a spped bump and lost the headlights, changed lights but they dont work, parking lights and everything else works fine just no juice to headlights.

 

I don't think there is one on the older years. Thats why everyone upgrades the harness and adds relays.

Unless its one of the relays near the battery.

 

No relay. Is there not a circuit breaker somewhere? Alot of older cars had it built into the headlight switch. When they got older, the C.B. would get weak and the lights would flash on and off or just quit working. Parking lights are on a seperate fuse.

 

Yup, no relay on the older XJ's. Just a fuse. The problem could be the headlight switch itself.

 

Breaker is built into the headlight switch. Something came loose when you hit the bump, start by checking for power and ground at the bulb socket and work your way back to the switch.
