Question about 1990 Chevrolet K1500

Where is the headlight relay on a 1990 chevrolet k1500?

My high beams are not working. I have replaced the dimmer switch and the light switch. There is a clicking noise like a turn signal when I turn on the high beams and the light switch gets real warm. I was told it is probably a relay, but I can't find it.

In the fuse box under the hood, if it has tilt stering it is the multi function leaver( signal switch) the wires get pulled from moving tilt and start to short out. take cover off of steering coulom and you will see the burnt wire. I would just re soder it instead of buying a new one.

Check your DRL relay that is located in the fuse box. Also check the connector under the battery box for corrosion. (Not a smart place to put a connector) GM really messed up with the wiring on the 98-00 cavaliers headlights.

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.

Why don't lights work?


Both the headlight switch and the BCM provide a ground, or control circuit, to the headlight relay coil circuit for manual or automatic headlamp operation. When you place the headlamp switch in the OFF position, and the ambient light sensor indicates low light conditions, the BCM energizes the headlamp relay for low beam operation. You may switch the headlights to high beam by pulling the dimmer switch handle toward you until the dimmer switch is activated. When the dimmer switch is placed in the HIGH position, the indicator lamp input to the BCM is pulled low. The BCM then sends a class 2 message to the instrument cluster in order to illuminate the high beam indicator lamp.

Low beams not working but high beams are on a 2000 chevy metro


The headlight relay provides power to the dimmer relay, then power goes thru a fuse for each light for each circuit (4). The low beam fuses are in fuse block 2. The dimmer relay is controlled by the daytime running light module. The headlight and dimmer switches send signals to the DRL module. You may need a shop manual to troubleshoot the circuits.

Low beams not working, but high are..


Year and model ?
Can you turn the headlights on and get the high beams, then nothing on low ? Or just get high beams when you pull on the dimmer switch ?

Its reversial for me my high beams wont work what


Good day:
the following is what you can do to test to see whats going on
turn on the headlights,put in high position
2.leave light in high, disconnect the head light dimmer switch, connect a fused jumper between head light relay supply voltage circuit of the dimmer switch and the control circuit of the head light relay. if the high beams come on then replace the dimmer switch, if the high beams don,t come on then.
3.use a fused jumper across the battery positive voltage supply circuit and the switched high beam voltage supply circuit. if the high beam come on now replace the head light relay, if the high beams don't come on then you will have to replace the LH I/P fuse block. I would most likely say that it's the relay just because of the year. I gave you a lot here I hope this helps

Head lights on 1990 jeep wrangle won't work


Ckeck the headlight connections they are notorious for corroding. Check the ground connection for the lights. Pull your dimmer switch back as if you were flashing a car to pass and see if they work there. If they do you have a dimmer switch problem.
