headlight relays (nxt to battery) or the actual switch in the car ...check you have 12v at the red wire behind the switch...could even be the switchable relay the headlight wires run to with a purple an white wire
relay in the hood fuse box HDM relay (Headlamp Driver Module)
First check the fuse if none of the lights even come on. If the lights come on but do not flash then the flasher relay is defective and needs replacing. If the fuse, light bulbs, and flasher relay are good then the turn signal switch may be the problem.
i had same problem its the relay in the fuze box under hood. i got a relay at dealer for 50 dollars.
to the right of the steering wheel there is a fuse cover and 3 or 4 relays, turn hazards on and feel which relay is clicking, if relay not working, its the tall looking relay,
The brake lights in your 1983 Nissan pickup truck are controlled by the brake light relay switch. When the brake light relay switch malfunctions the brake lights will stop working.
Could this be a problem right in the body control module ??
I'll check for a blown fuse(fuse relay box), ground problem, and your bulb.
The brake relay switch is bad.
i just had that same problem on my 106 found it to be the relay that was causing the problem!
check the fuse and the park lamp relay
Where is the turn signal flasher relay placed on a Ford Falcon EL?
Both bulbs are out, wiring problem, switch problem, fuse, relay.
