GM Repair Questions? Ask a Mechanic for Answers ASAP
Hello & Welcome,
Does this mean that the brake lights and the backup lights work, or are they out too?
I am so sorry - my wife had a kitchen emergency that I had to take care of.
Let me check the schematics and see what I can find.
Do you have a test light or multimeter you can use to do some testing?
OK - Now we are getting somewhere. Most of those lights are driven by the same circuit. Here is the schematic.
I have highlighted the fuse and the switch that controls most of the lights.
What I would do is check the fuse with a test light or multimeter to see if power is coming into and going out of that fuse. If that is OK, it would be time to check the pins on the headlight switch to see if it is working.
If you don't have the test tools, you can just check the fuse visually (look at it) and see if it looks like it is blown.
Please let me know what you find.
Take Care, Greg A.
That would be the next suspect. But I could not say without testing. I would recommend that you get a cheap test light or meter (they are only $5-$10) and make sure power is making it into the switch (at pin H of the schematic) and then comes out when the switch is turned on (pin S of the schematic).
Take Care, Greg A.
Sounds like a plan.
I really think it's the switch. I looked it up online and found that the switch assy is available at the local parts store. I will buy it and see if the new one works. If it doesn't, I'll simply take it back. I'm almost positive this will work.
I'll click accept as soon as I find this works.
As a quick test, you can carefully put a jumper wire from pin H to S and see if that makes the lights come on.
Did you place the jumper wire between the two pins I mentioned above, as a test, before replacing the switch? Did you get a test light or multimeter to do some testing?
Ok - Thanks.
You might want to consider an inexpensive multimeter too.
A good test light or multimeter comes in pretty handy most times to figure these things out.
I am glad you got it worked out and that I could help.
