!997 Chevrolet S10 headlight problem

Been there done that. Lights still went from low or high beam to no daytime running light when I took the fuse out. I also tried to hot wire across the relay and that didn't help. Any other suggestions? Know where I can get a copy of the headlight wiring diagram anywhere?

I have had the same problem with my 97 S10. I looked at the GM iring diagram and found that the headlight circuit runs directly through the main headlight switch with no fuse or relay at all. The high low beam switch cannot shut the circuit off completely and therefore make the clicking relay sound that is heard. The daytime running light module looks for a headlight on signal and therefore shuts off the running lights. So when the headlights cut on and off the clicking you hear is the day time running light relay, turning them on thinking you are shutting the headlight switch on and off. Inside the headlight switch itself is a thermal metallic circuit protector similar to whats inside a flasher switch. This is the only logical place for the headlight circuit to cut out since it is a directly wired circuit as explained before. Replace your headlight switch for less than 20 bucks from autozone.

Ya know it kinda sounds like the headlight switch that switches from high beam to low beam has a bad contact. You don't have one of those 4-beam modules that turn on all 4 lights on high beam do you? that thing screwed my whole headlight system up, I ended up throwing it in the trash.

I have the chiltons and haynes manual, I'm sure between the two we'll find a good diagram. I gotta get my youngin to open house at school, but I'll pull the books out and send you the wiring diagram.

My truck is actually a '95 C1500 but I understand that they were the same model from 88-98. I have 2 problems - both electrical. On a recent trip, I lost both low beam headlights at the same time. ...


There could be a fuse for each low beam light either under the hood or under the dash. If not, then prob both low beams are bad.

If you have daytime run lights, the following may be of help.

There is a daytime running light module that controls both low beams and the daytime running lights. The low beam bulbs may be OK. The high beams will work fine as they are not controlled through the module.

It may be possible to disable the daytime run lights by cutting the yellow wire going into the module and then connecting it to ground. Tape off the other end.


This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

2005 trailblazer headlights go off ocasionally


the click you are talking about is the high beam relay.
you nedd to get a tester or voltmeter and check the sockets for 12v.
there has been instances where both low beam bulbs went at once.
do the daytime running lights work?
if not,supect the daytime module...it is also wired into the parking brake.
if you put the park brake on first,then start the vehicle,the dtr do not come on

Headlights wont work


Well...lets start with the obvious. Check fuses and NEVER piggyback any stereo or security stuff into their fuses...you dont want the lights to shut down during a night drive!!
Check under the hood for a relay center...also has some fuses there as well.

The Daytime Running Lamps are a "straight through wiring configuration". Doubt it even goes through a headlight switch at all.
But the regular lights do.
Unless you've worked on the front of the car and forgot to plug the headlights back in, do this...
Turn the light switch on...looking at the instrument cluster , can you make the high-beam-indicator light come on?
As you rotate the headlight switch knob...does the instrument panel lights brighten or dim? You probably have a faulty headlight switch...auto stores have them...they simply plug in.

perhaps i missed something here... lowbeams and daytime lights are about the same.... be that as it may... the merely obvious thing is that the low beams are burnt out.... next thing would be that the relay for the day time lights could be defective... it's often mounted on the firewall.

1997 Chevrolet Headlight problem


did you try removing the DRL fuse to disable the daytime running lights, and double check your bulbs and fuses for the regular headlights? I'm not much of a mechanic but I'll take that fuse box before messing with anything else.
