Headlight Switch - Troubleshoot & Repair - 1993 C1500 OBS Chevy - EASY DIY 

Good fix!! Stuff like this always happens at the worst times too. What ever grease/lubricant they have on the contacts inside the switch had dried up, so the contacts get resistive which leads to heat and enough of a voltage drop stuff doesn't work anymore. One tip: if you have any Dielectric Grease, use a thing layer when you have those push on wire to switch connectors. It's a great stuff to prevent flakey electrical connect from corrosion. Also helps spark plug boots come off easier. Take Care!

All I wanna say is thank you for your video. I followed you step-by-step and I was able to fix the switch on my truck. Thank you.

1990 Cheyenne Just started having this problem thanks for the video 👍

Thank you for posting this up. I have a 1994 gmc 3500 and it did the same thing. I wouldn't have known where to start to diagnose this issue. Again THANK YOU so much. Most helpful

Thanks my man! My 93 had the oppisite as you. Headlights were running fine, but my instrument lights would not turn on. Great video!! Much appreciated 👍

I’ve been smelling that burnt smell for a while now. Getting ready for a long trip across the mountain pass this morning, my lights started doing exactly what yours did. Will R&R once on the other side. Thanks for the insight.

This really helps me fix the same problem on my `94 c1500. Thanks for sharing!

Also in the summertime that hot melt glue you put on there it's going to get soft and when you go to turn your lights on it's going to fall out

Perfect! Thank you for your expertise! 😁

Thanks for the informative video,I'm having the same problem on my 94 Cheyenne,ordered another switch today

I got 97 GMC Sierra and for awhile now my daytime running lights stopped working and I replaced the little black relay underneath the dash hoping that was the fix but it wasn’t. I ignored until my headlights started going out randomly while driving. I sometimes have to jiggle the switch just to get them to come on again but it’s getting annoying and it’s dangerous. So I’m going to buy the switch today. Hopefully that fixes it.

Also, you do NOT need to pull the radio for this fix. Everything stays in place.

Thanks my parking lights just went out tonight....fuse is still good

Shockingly this helps il look into it since mine was smoking and burning parking lights wont come on at all

Thank you sir!

Why don't you try it first before you snap the dash back in

Just happened to me. It's like you were there with me 😂

I had the same problem on my 1994 cheyenne, only the dash board dimmer switch is actually the culprit, it gets hot enough to burn your fingers when you turn it up to light up your gauges, and it weakens those mounting screws on the back of the dash bezle, it might be the reason why your headlight switch failed, the dimmer switch has cooling fins on it but theyre not worth a 💩, theyre just an aftert thought.

I was in town yesterday pulling my cargo trailer to have trailer checked out for parts it will need. I have a 93 Chevy Silverado and I knew before I left home that I had no lights---thus I only drove with plenty of sunshine. I get to the trailer business and explain to the owner my problems. And so he and an employee checked it out and he said that the light switch is bad. I walk to the Auto Parts Store and buy a new switch, install it and turn it on and it gets hot and started to smoke so I quickly turned it off and took it out. I took it back and explained what happened and they sent for a new one. I walked back to my truck and waited for it to get there. I got the 2nd light switch installed and I turned it on and only the headlights and front lights are on, but no rear truck lights and no trailer lights.I walk back to the cab and feel the light switch and it's hot again but not smoking. So I quickly turned it off and took it out and I was burned by it, it was so hot. So I'm back to where I started with no lights, just blinkers and brakes. There's a problem with the truck wiring somewhere and now to hire a business to search for the problems and fix them.

Im having a problem with my dome lights and the light under the dash neither work any help

94 Chevy Astro. Way different configuration on my van.

Is the super glue always necessary?

Just one of those times it's worth paying extra to have the problem behind ya!

On those mounts I always reinforce with JB Weld.

Thanks it help a lot

god bless you brother

Could this be the reason my brake lights no longer work when I turn on the headlights?

she dreams in color she dreams in red

That looks just like my Chevy, even the dash carpet and my headlights not working!

Have running lights but no headlights

I changed my light switch and still no dashboard lights

I have the same year truck. Question: Is the switch illuminated when the lights are on?

Does anyone what size the 4 small screws those are that hold the switch

👍

Does switch effect tail lights?

Can you tell us the part number ???

Does anyone out there know of any videos on how to test a neutral safety switch for an auto transmission on a 94 Silverado k1500. I can find everything else on a manual transmission but not an auto. Any help sure would be appreciated.
