On a 1999 GEO Tracker, a bad fuse can cause the headlights and dash lights to blink. A bad voltage regulator or alternator can also cause lights to blink and flicker.
Blinking lights on dash and exterior lights may indicate a bad ground wire or a faulty headlight switch. Both would cause those problems.
Possible ground issue at the taillights.
Most likely a fuse.
A bad ground wire will cause dim headlights, or will cause lights not to work.
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.
probably the fuse is blown.
Check all of your blinker lights. There are two in each tail light, one in each center signal, and one at the corner of each headlight, a total of 8 lights should blink when you have the flashers on. If a bulb is burnt out, it will increase the blink rate. Also, installing LED's in the tail lights will cause the blink rate to increase.
Most likely poor wiring.
I would replace the headlight switch as Ford has had their share of these problems.
If by "dim headlights" you mean low-beams... the bulbs are bad and must be replaced.
They are either the wrong bulbs or one of the filaments is burned out. The bulbs should have two filaments. One is illuminated when the lights are on. The other is brighter when the brakes are used.
If you have no battery then you have no power.
You will have to check all the door sensors.
A mis-wiring or short circuit somewhere between the controls, fusebox and lights.
yes it will also cause them to blink off & on and
Faulty ground to the dash.
sometimes the head lights and tail lights may be fused separately,check your fuses.you could have a bad ground.thats just two places to start.
Fog lights. Headlights and hi beams can make foggy conditions at night much worse because their light tend to illuminate the fog directly in front of your vehicle. Because Fog lights are much lower on the front of your vehicle don't cause this problem and you can see a bit futher. the fog lights
Some cars have a knob for the headlights. If this knob is turned left or right when pulled out, it changes the brightness of the dashboard lights from off to full brightness.
Check the fuses.
your alternator is going bad
The dim lights on a 1994 Grand Prix could go out when the headlamp switch is on if there is a short in the wiring for the headlights. There could also be a problem with the bulbs themselves if they were touched during installation. The oils in the fingers can short out new headlights.
First thing you want to check is the dimmer switch to see if it is turned all the way down.
Headlights need to be on for starters. Blown bulb, relay, or switch.
