SOURCE: No headlights, or dash lights.

check the ground cable at the battery , youll see a break in the ground wire at the battery box, check to make sure the bolt is tight and not corroded (the break is the ground for most of the lighting )

SOURCE: headlights flicker all the time

Hi, my name is ricky and im 24 yrs old and from Bronx, N.Y . I bought my 03 impala in 04 and i had the same problem in 2007 in which that clicking noise happens. The headlights flicker, and even the gauges inside the car would flicker at times. It has nothing to do with fuses or a relay, please dont spend money on that b.s. like i did..lol I will try my best to explain what i did so that you can save some money and time. READ EVERYTHING AND USE ADVICE AT YOUR OWN RISK.
1st of all - I went to a junk yard/auto salvage yard to find a USED part that i needed. Often there are good parts from cars that have been totalled.
2nd- What i asked for was a Body Control Module. This controls most of the electric issues you are having and costed me about 50 dollars compared to a new one that was over $200 and reached up to $500.
3rd- I went head first under the steering column and found where the BCM was located. Poke around to find it cause it is def. there, hidden well. It doesnt take special skill to remove it or find it.
4th-Replace the BCM, but be advised that after you do this, your car might not crank over.My car did crank over because i installed a automatic starter previously so i could have started it with the remote start.
5th- you MUST take the car to a chevy shop so they can Program your car to the body control module this costed me about $250.
All together this information has to help you in someway.
If you have further questions or would like to make a comment, then e-mail me at " gyalflexfameh@gmail.com "
I hope this helps...im not saying it is a 100 percent guarantee for you, but i had this same problem recently and this was the answer to my problem. By the way, never buy a american car again or a GM product for that matter...Kudos

SOURCE: 1986 Chevy Caprice Classic Horn not working

Diagram should be on the inside of the fuse box or relay cluster lid/cover. If Test light has 1 wire and a sharp tip? Yes, but only if you push the horn button too ;-)

My guess is that the horn lost its ground, but you can check this with the light. The horn only beeps when both GROUND and Pos 12v are present. The horn button gives the relay 12v to close, and the relay gives the horn 12v to operate. The ground is always connected.

Connect tester clipwire to 12v source (battery, headlight (has to be on) and touch its tip to metal of car. Does it light? Good. the tester is working and the 12v is a good source.

Touch one of the 2 horn connection or wires (poke it thru the plastic - why tip is sharp). Does it light? Touch the other, does it?

If both light, (1 will be brighter) we can assume the horn coil is good and it is getting a good ground and I was wrong (it happens... but not often). The side that is BRIGHTER is the ground wire side.

Now have someone mash the horn button. Do you hear a tiny click? That is the horn relay. If not, look for the horn relay fuse and replace it. If you DID hear the click, the relay coil is good and is trying to switch 12v to drive the horn.

Now is time to locate and replace the horn fuse or the relay may have bad contacts. Look at the other relay part numbers in the cluster and see if there is a match for the horn one. Swap it out and try the horn.

Hope this all helps. To 'test' the horn, touch the dim side again anf listen for a scratching sound. That is the 12v going thru the tiny bulb in the tester (a resistance) and trying to drive the horn.

Good Luck!

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.

Headlights won't turn off


The weird noise is the relay for the headlights. You need to locate the relays and replace them. They are in the fusebox that is under the hood.

1986 Supra. Head lights pop up but does not turn on.


the headlight pop-up circuit is different from the lights themselves. Check the headlight fuses in the engine compartment fuse box. If the fuses are good then check the headlight relay. It is in the same fuse box just behind the headlight fuses. (The headlight relay is the second relay from the right side of the fuse box. the relay at the far right is the electronic fuel injection main relay.)

Hi, the harness is not reconnected properly to the fuse box. You have crossed the relay circuits. Look at where the horn and headlamp relays are on the box, and remove the connector under that spot. Maybe it needs to rotate 180 degrees.

Car would not start, cleaned all the battery connections and started the car, now headlights do not work, parking lights do, i have power to bulbs on the middle wire, no power to the outside wires on...


Most cars have a Headlight relay and within the relay different terminals will split the power to parking lights, headlights, etc. It is possible that part of the relay burned out while the balance still works. You may have a fusible link (wire) to the relay box for just the headlights. A good Autoparts place should show the requirements.

I suspect the bad connection on the battery caused the Starter to draw power or a ground through the easiest path of least resistance. This shorted the grounded Relay.

Headlights power


check your fuses and look under the hood for a black relay box and it might have a fuse in the box for head lights. The cover that comes off of relay box will tell you (inside) what each relay or fuse is for.
