SOURCE: 2000 mustang headlights are dim

Check the headlight relay.Little plastic cube about 1 1/2" square,usually black or dark brown and white ink numbers printed on top.Bottom has blades sticking down into the wire connectors.Location will either be under the dash or under the hood,not sure exactly about mustang There will likely be other relays in the same location,and many times you can match up two relays with the numbers printed on top,and swap the relay with say...the wipers' relay,just to see if it is a bad relay.Cheap ($0) and a check worth doing
I hope this will solve your issue.

Good Luck.

If my solution proves useful please accept it.

Check headlight lamps... then follow the wiring from the bulb connections back and make sure you're getting a good solid ground connection. It may have a loose, broken, severed grounding wire.. it's usually attached to the car body at some location not far from the headlights.

SOURCE: 89 Thunderbird, no tail lights

There are 3 wires behind the headlight switch brown+, brown-, and white. All 3 wires are normally clamped together.

I'm not sure what the white does, but when the two brown wires are connected, your parking lights work like they should.
If the brown wire leading from the bundle of cables grounds to the metal switch mount, it will blow your fuse.

If your parking lights don't work, and your rear lights don't come on with the low headlights, these 3 wires could have come undone.

Why dont you start by checking the fuses for headlights refer to your owners manual for the location of the fuse box for your car. if the fuses are good then replacing headlight bulbs to both headlight assembly is your next step.If after replacing both headlight bulb you still have the same problem then you might have other electrical issues.

No turn signals, 1 driver brake light bad, ABS light on. 2002/2003 CVPI


Sounds like you have 'ground' issues. Apply the brakes using a broom stick or more apropriate tool so that the brake lights are activated. Then go to the brake light that is not bright enough. using a test-light with a sharp pointed probe, poke the ground wire close to the bulb (usually a black wire) make sure the test light is attached to a grounded bolt. if the brake light gets brighter with ground added, you need a new ground wire. Splice it in to the existing wire & attach it to a bolt. Lights should work better with proper ground. (each bulb has a positive post & neg. post, don't add ground to the side with power coming through it from Battery (+)(red light on test light) - probe wires FIRST with test light to find (+) POS. Hot wire, and leave that one alone.

That sounds like you have 1 ground wire, 1 wire for the low beam, and 1 wire for the high beam. If the car has the standard halogen headlight bulb I would recommend replacing it and seeing if that fixes the problem.

1997 chevy s 10 driver side dim head lights bulbs new and grounds good


Pull and replace the fuses for the headlights. Its likely a dirty contact. To be sure use a volt meter and measure the voltage at the headlight. Should be close to the battery voltage. If its low and its not the fuse start tracing back the wire from the headlight until you find the bad connection.

Hi, fuse 10 in the car runs the left bulb. If the fuse it good, it must be the wire or ground connection. There is no relay in the circuit.

How do I replace the headlights on a 2003 montana van?


dim headlights are almost always caused by a loose ground or corroded ground, the ground wires are near the head lights attached to the inside of the fender, check them, pull them off and clean them and the surface they attach to with sand paper.
