It is possible that both of the fuses are bad for the low beam headlights and the cruise control. A loose ground wire could cause the fuses to blow.
Had the same problem. Found it to be a bad ground wire for the headlights. There are two ground wires for the headlights, both are directly below the battery. You can see one of them if you remove the drivers side headlight. It is right behind the radiator hose. The other is a few inches from that one.
That can happen when there is a bad ground to one of the lights.
Usually dim headlights are caused by a poor ground connection.
Bad ground on the brake lite circuit.
Possible ground issue at the taillights.
i had a problem with my 99 grand am...the lights were pointing at each other towards the ground about 10 feet in front of the car...there should be several screws above or behind the headlights on either side...take it out on a road at night and have someone sit in the car while u adjust the lights with a screwdriver but be easy because the plastic piece that surrounds the headlights break easily.
The headlights probably have a bad ground. the alternator is probably going bad.
This will happen if the ground terminal for the brakelight bulb is connected to the power side by accident. If you have a 3 wire socket or light assembly with GROUND, TAIL, and BRAKE wires two of them are wired incorrectly. When the headlights are off the brake light is finding ground thru the filaments of the headlights. Since the headlights have much heavier filaments, they provide a good ground for weaker brake light. When power is on the headlights the brake light will have power on both sides, so no current flows and it goes out.
Bad battery connection, bad starter connection, bad negative ground to engine, battery to fender grounds, etc.
Your headlights need to be adjusted, you do this by popping your hood and adjusting them by the screws on the top or bottom of the headlight, most of the time you will need a screwdriver to do this.
The most common problem for headlights that go out. When you hit a bump in the road is a loose ground wire. The ground wire may need to be taken off and cleaned.
A loose or corroded ground wire can cause your 1995 Jeep headlights to blink on and off. Make sure the ground wire is tight and free of corrosion.
If there are not "short's to ground", you probably have a faulty circuit breaker for the headlights.
There is no ground wire.... it grounds through where it touches the engine
They need a better ground going to them. There not grounded good.
Low alternator output or weak ground connection. Have the alternator checked.
I had a similar problem with a Pontiac some years back. It was a bad dashboard ground. It may not be it, but I would start there.
The most common cause for dim headlights is a bad ground connection. Headlights draw a relatively large amount of current. Any loose or corroded connection in the circuit will drop a large amount of voltage, which doesn't leave enough for the headlights to operate properly.
Often this type of behavior is caused by a bad ground for the lighting circuit. Check the ground circuit for the brake lights.
I'd be tempted to replace the head lamps before I replaced the switch. You're looking at a cost factor of about $25 to replace the lamps vs $65 or $70 for the switch. Be sure to check for the obvious things like fuses or broken wires first. Could be there's a loose, broken or dirty ground connection to the headlights.
Check the ground wire to the tail lights.
I might start by checking the ground wire of the taillight assembly. Make sure there isn't any rust that is preventing a good electrical connection to the chassis ground.
There are several things that can cause your 2003 Kia headlights not to work. The most common cause is a loose or corroded ground wire.
