93 suburban headlights flashing off and on.

My headlights go off and on in both high and low beam. Sometimes they stay on longer than others. I did replace the headlight switch and it still does it. All other lights work well.

Had same thing and noticed headlight switch gets very, very, hot. Lights flash after lights have been on about 45 minutes, and noticed burning smell. Clamped a 12-volt fan to emergency brake pedal so it's aimed behind dash and facing up toward switch, and wired it in. Problem solved. Others have mentioned the switches on similar-year vehicles also get hot which leads me to believe it's a design issue. Switch can't handle the current going through it and eventually the heat causes it to fail.

SOURCE: My headlights are not working, but shows my high beams are on

Low Beam Fuse may be bad.
Low Beam relay position is bad.
Stalk that controls the high/low beams/cruise/lights is bad.
Low beam filament may be bad in both headlamps.

SOURCE: 2002 Impala, headlights work however they blink

This may be the start of a worse problem that the Impala eventually developes. The Body Control Module has a design flaw along with the Passlock anti-theft system. You may get away with just replacing the BCM for now. It needs to be reprogrammed at the dealer and the car will not start if you replace the BCM without reprogramming it. I would also recommend against replacing it with a remanufactured one. Repair cost is going to be around $500 at the dealer.

If the Passlock system is also at fault, add another $500 for a new ignition switch and cylinder. If you haven't experienced random starting problems yet, they are coming soon. When you turn the key, nothing happens. I thought my 2002 Impala may have been immune to these problems that I've heard about constantly, however, at 90,000 miles, it became "possessed". The symptoms started slowly and got worse. Beside the interior lights flashing like strobs in the middle of the night (while the car was not running), the headlights would occasionally click off and on a few times while I was driving at night.

The relay switch you hear clicking is the Battery Rundown Protection relay. I'm suprised your battery hasn't drained to the point where the car will not start in the morning.

1994 pontiac grand am high beams work but no low beams, possible relay issue?

Sounds like it's in the actuator itself - the part that you move on the steering wheel or dash to put the high beams on or the headlight switch itself.. Find the ground wire on the headlights and run a new wire from that directly to the body somewhere so it gets a good ground, or directly to the neg side of the battery.

My headlights don't work, but the brights do. What caused this and how can I fix it?

Every headlamp has a bulb inside that has two filaments one for high beam and the other one for low beam, if any of those filament is cut then that beam (High or low) won't work. If your high beam work then your fuse it's ok, so you can visually inspect your headlights bulbs for broken filaments. remove bulb socket and remove the bulb carefully to inspect the filaments. if the filaments are atacched from one terminal to the other then the bulb it's ok, if not replace the bulb.

2005 Dodge caravan. The Headlights are not staying on. When we turn the switch, sometimes they come on, sometimes they do not. It's getting worse.

Hello, on the van you have a high beam fuse and relay. On the low beam you also have a fuse and relay. Check the fuse/relay panel for a blown fuse controlling the low beam lights. If you do not find a blown fuse have some one to turn the key on and turn on the high beam lights. During this time locate the low beam headlight relay and place your finger on top of relay, have the other person to switch from high beam to low beam lights. You should feel a click in the relay when they make the switch from high to low beam. If not replace the relay and the problem should go away. Hope this will help you.

Thanks

93 Camry Headlight Switch

From the symptoms you describe it sounds as though your headlamp switch is dirty, broken or out of adjustment. I would disassemble it and find out what is going on.
