Headlight relay


On your truck, the headlight switch sends a ground signal to the central timer module. The module powers the headlights and other circuits.
The module should be behind the driver side kick panel under the dash.

see this steps and fix it use the VOM or DVOM. God bless you
The Cause: Most likely no voltage to the headlights because of a bad headlight relay, fuse, module, headlight switch, dimmer switch or wiring fault.
To figure out what's causing your problem, start by inspecting the main fuse for the headlight circuit. See your Owners Manual for the location of this fuse. It is often located in the power center in the engine compartment, but may also be in the fuse panel under the dash.
fuse1b.jpg If the fuse has blown, replace it with a new fuse (same amp rating) and try again. If the fuse blows immediately, there is a short in the headlight circuit that will have to be found and repaired before the headlights will work. If the fuse does not blow and the headlights work, problem solved (for now). There may be in intermittent short or overload that caused the fuse to fail.
If the fuse if okay, use a volt meter or 12-volt test light to check for power at the fuse. Most headlight circuits are on (powered) all the time, so there should be voltage to the power side of the fuse. No power at the fuse would indicate a wiring fault possibly in the fuse block or in the wiring between the fuse block and the battery. You'll need a wiring diagram to trace the wiring circuit and find the fault.
relay_1a.jpgIf the fuse is okay and there is power, the next check would be to find the headlight relay or control module. If the system uses a relay, pull it out and shake it. If anything inside rattles, replace the relay. Or buy another relay and plug that in to see if that restores power to the headlights.
On systems that use a module control module or daytime running lamps, about all you can do is eliminate other possibilities such as wiring faults, a bad relay or headlight switch first. If the module is getting power when the headlight switch is turned on, but the headlights fail to come on, the problem is likely a bad module. The module may be located in the front area of the engine compartment (common on Fords), under the dash or elsewhere in the front of the vehicle. You will probably need to refer to the vehicle service literature to find the module's location.
If the headlight relay or module do not receive voltage when the headlight switch is turned on, a bad switch is your problem. Switches get a lot of wear and tear, so it's not unusual for a switch to wear out after many years of service. Replacing a headlight switch can be difficult depending on whether is it located in the instrument panel or on the steering column.
If your headlights work on low beam, but you have no high beam, or they work on high beam but there is no low beam, the most likely cause is a bad dimmer switch. The dimmer switch is integrated into the steering column mounted headlight switch on most vehicles, so if the dimmer is not working, you will have to replace the entire switch.
DO NOT attempt to replace a steering column mounted headlight switch without first disconnecting the battery and waiting at least 20 minutes for the capacitors in the airbag circuit to discharge. The steering wheel will have to come off to replace the switch. Crossing up the wrong wires in the steering column could set off the air bag and cause personal injury.
If a headlight switch looks like it will be difficult to replace, don't try to do it yourself. Take your car to a dealer or repair shop and have them replace the switch for you.

Daytime running lights not working


Assuming this is an LX, check 7.5A fuses 9 and 5 in the driver's underdash fuse/relay box. Fuse 9 applies power to the DRL indicator light in the gauge assembly which connects to the DRL control unit. Fuse 5 supplies power to the DRL control unit when the ignition is on. Also check 100A fuse 41 in the underhood fuse/relay box which supplies power to the headlight relays. Setting the headlight switch to HEAD causes the headlight relays to close and apply power through 20A fuses 45 and 43 in the underhood fuse/relay box to the low beams. Low beam power also passes through the DRL diode to close the high beam cut relay and prevent high beam use during DRL operation.

Headlight relays


There are no relays as such. You need to check 10A fuse 11 in the junction box and 20A fuse 12 in the power distribution center. These are the source of power to the central timer module which controls headlight operation. If the fuses check good, start the engine and set the headlmp switch to HEAD. The headlights should come on with either low or high beam depending upon the position of the multifunction switch. If nothing happens, the central timer module probably is defective but the multifunction switch also could be defective.

Which relay supplies power to headlights on a 1997 Ford f150. where is the DRL relay and fuse located


The relay is integral to the DRL module. The module is usually near the driver's side headlight and is powered by fuse 9. Diagrams are below. Please let me know if you have questions.

Please let me know if this was helpful and if itsolved the problem! Also if the information provided was helpful, please clickon the appropriate thumbs to make us aware that the problem has been addressedor that the information provided helped you with the problem.. Thank you andGood Luck.

The SSFR (Solid State Fan Relay)Cooling fan relay is located on the left front inner frame just behind the radiator.
The radiator coolant fan relay is located on the inside front of theengine compartment near the left headlight assembly. You have to removethe air filter assembly, then look for a simple square relay with 4wires running into it. It is mounted with 2 screws. It is the onlyrelay at that location. If it has burned, you will need to replace thepigtail wiring harness.
Remove the air box beside the battery a10 mm bolt and the relay is a four prong square box bolted on the framewith two 8mm bolts

Some are located under the drivers side headlight, Removeair cleaner assembly, remove headlight module, remove (plastic)cover(air intake0 with a phillips screwdriver, locate module, removewires (red tab). Some are riveted (like mine), carefully drill ourrivets remove module, install new module,

2001 Dodge Durango, headlights flicker


I had a similar problem on my 2001 Caravan. Turned out to be a loose connection between the frame control module and the fuse box. I unscrewed the frame/front control module from the fuse box and bent the tabs slightly to make better contact. Then tighten down the module securley. Need star driver to loosen screws

98 ford taurus headlights will not go off


either the headlight relay is stuck on. or the daytime running light module or relay is bad. to confirm find the relay center and switch the headlight relay out with another relay with the same part# on it. there should several in the relay center with the same part #. If this fixes the problem get a replacement relay. if not try switching out the relay for the daytime running lights. if no dice then unplug the daytime running light module.
