SOURCE: where is the headlight relay located?

Headloght switch or dimmer HI-Lo switch is what I would look at. The power to the headlights goes through the dimmer switch before it gets to the bulbs. No relay!

SOURCE: I have a new headlight relay for my 1997 volvo 960

The headlamp relay is located under the dash to the left of the steering wheel. If it is the original relay, it will say "headlamp relay" on the side of it.

SOURCE: which relay supplies power to headlights on a 1997

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.

SOURCE: 1998 buick century only high beams and turn

The Buick Century is equipped with a multi-switch. This switch is an all in one switch that controls your cruise control, windshield wipers and turn signals in one switch. This switch also controls dimming and brightening of your headlights. The dimmer switch is simple to replace, and all you need is a phillips head screwdriver to complete the task.

  1. Removing the Steering Column Shroud
    • Removing the dimmer switch starts at the steering column. To plan this task out, access the steering column by removing the screws holding the steering column shroud in place. This will expose the turn signal lever. Remove the lever by twisting it forward, and pulling it out of the switch.
    Removing the Dimmer Switch
    • The switch is held on by two screws and a wiring harness. The wiring harness can be removed by prying up on the locking tabs and pulling the connector out of the socket. The two screws can be removed with a phillips head screwdriver. The switch will slide out. To install a dimmer switch, be sure to repeat these steps in reverse order.

Where is the headlight relay located on a 2002 PT Cruiser?


Did you check the fuse box inside the cabin ? The book says the relay is in the fuse block but does not give a description.
Keep in mind the headlight relay only affects the headlights. The other lights you mentioned are on different fuses and not the headlight fuses.

2001 chevy impala overhead light wont turn off


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.

2001 GMC Sierra headlights won't come on. Located 3 each 10Amp fuses that were blown and replaced them, however, headlights didn't come on.


what fuses were blown and replaced? Theres a TBC fuse under the hood, along with a Headlamp Relay. Theres a R HDLP and LT HDLP fuses, make sure they are getting power, and are good. If the LT HDLP and RT HDLP fuses are good AND getting power, then the TBC fuse and the relay is good. then I would suspect the Hi-Lo dimmer switch bad. The LOW beam ground wire is YELLOW, the high beam ground is PURPLE. see if high beams work, if they do, then I suspect the dimmer switch is bad.

Fog lights don't work


First need to test for power at a fog light. If no power, then I would check fuses. there will be a fuse box under hood and one under the dash. Take a test light and test all fuses on both sides of each fuse. Could be called running lights, aux lights, driving lights, etc. Any fuse that does not have power on both sides is suspect. Note: the headlight fuses cannot be checked unless the headlights are turned on. the owners manual will also tell you the location of the fuse box and which fuse in the box to test. Could also have a relay that has failed , it will be in the underhood fuse box.
