Where do I find headlight relay switch on a 85 Nissan extended cab p/u


Pretty sure there is no relay for the headlights. There are two 10 amp fuses in the fuse block, one for each side headlight. The power to the fuses is directly off the black fusible link (in your fuse link box, under hood, by the battery). Then the fused wires go into the headlight switch, and with switch on, out to the head lamps.

First check if the fuses have power to them. Hot at all times, so key can be off. If they have power, fuse link is good, so possibly a bad headlight switch or dimmer switch if no headlights..

Can someone please tell me where to locate the headlight fuse relay in a 2004 Hyundai Santa fe? My headlights went out and the fuses are both good but I cannot find the relay to replace it.


Things to check; common wire for ground may be disconnected so take the common wire and run a jumper to the battery.
lights could be bad they wear out too. Substitute
a known good lamp in both sides to see if this fixes problem.
Headlights also go thru the dimmer switch so run headlights to battery with a jumper wire. This bypasses headlamp switch and dimmer.
Consult the owners manual for fuses,relays and their locations. One fuse box is usually inside passenger compartment and another under the hood.
Hope this helps.

Toyota hiace lights wount come on


Check the dimmer switch! Head lights should still work if dimmer! But no interior dash lights! Fuse for lights is under hood in fuse center! If it is the headlights I would check the switch and if applicable the relay! I assume you have checked for ground at the light and power at the headlight fuses!! Good luck

I have no low beam headlights. already checked bulbs, fuses, relay and dimmer switch. can you help?


Before you replace the #46 HDM relay (in the fuse block under the hood) try exchanging it with the #45 cooling fan relay and see if your low beam lights work. If they do, the HDM relay (actually solid state module, not a relay) is bad.

Cant find headlight fuse 1992 chevy suburban


If the high beam lights work by pulling on the dimmer switch, you are bypassing the headlight switch.
There should be a circuit breaker inside the headlight switch which could be faulty.

Low beams stopped working


There maybe a headlight relay under the hood, most are in a protective box. There may be a fuse also under the hood. Ck the fuse if there is one and tap the relays with you low beams set to be on. Good Luck, Ned

Where is the Relay Switch on a 2002 Monte Carlo? My headlights stop working...someone said it could be my Dimmer Switch, but everything on my Dimmer Switch works....So I thought I would start with the...


Under the hood there is 2 relay's. One for each side. First check to see if there is power at the fuses. If yes then pull the relay's out and see if there is power all the time with the key on. Then see if there is power with the switch turned on. There should be 2 powers with the switch on. If only 1 power then the switch is bad. Let me know how it goes.

Headlights in 1990 ford bronco/full size


Bronco uses a RELAY switch under the hood. Is that what you replaced?

Swap it with the A/C RELAY switch (they are the same) to check it.
