Is it possible for a relay for your turn signals and hazards to fail on three of the lights but still work on one. my passenger front works but it's the only one on both signal and haz. lights. 2004 GMC Canyon. scratching my head on this one any help would be great. frustration has set in LOL
My starter was bad but the mechanic replaced a switch commutateur interrupter, now my passenger side turn signal hyperflashes on the front, I have no turn signal on the rear. You can feel it in the relay switch located in my fuse box next to my dash. My starter was replaced, but why did they install a commutateur interrupter switch? And, why does the relay switch that they installed cause the hyperflash? Now, they tell me that they can install another switch that will cause the relay switch to stop the hyperflash. Personally, I think it's BS, why keep adding more switches?
@@siouxzee59 lot of auto mechanics who are only in business to lie and cheat the customer; not all but the overwhelming majority
@@siouxzee59 thank goodness for channels like 1AAuto and Scotty Kilmer who are out to help, not hurt
Best company ever. Sells the parts, shows you how! I've replace a ton of things on my car, including all window switches and all regulators. Thank you 1A!

Without this channel my truck would live at the auto mechanic shop. That’s not including the thousands I would spend. Absolutely love this channel
thank you very much for making this video! I tried reading a write up explaining how relays work and I wasn't grasping everything very well. but now that I have seen this video it all makes a lot more sense to me, it may be just that it's one of those things that you have to see in motion to understand better.. thanks again! 😀
LOVE the thorough explanation for how it works!!! Common sense explanations and down to earth testing for amateurs without expensive toys. LOVE LOVE LOVE IT
RUclips has saved me so much money on car repairs! 🙌🏾
Thank you for your video. That would have to be one of the best for a novice like myself. Now I can diagnose electrical faults with more confidence. Great job sir.
Very well explained different methods of testing relays; really liked how you took the time to explain the workings too. Great for amateurs like me.Thanks!
LOL. BEST DESCRIPTION, EVER!! Thank you. Also, I loved the "Honk Animation". I watched it five times. You made little animated sound waves, and the relay actuator closed! Brilliant!
Excellent video & detail. Like the fact you demoed other methods of testing. Thanks.
Thank You so much for this video.
It helped me sort out something that had been driving me crazy.
Did not realize that inserting it backwards will 'randomly' break stuff.
Great info!!! I have a failure started w my drivers side door locks. Finally took entire down to nothing. So now I shall go out to check fuses and relays before I call anyone. Tks!!!
Your explanation on relays was awesome.
Very inclusive video of all the methods needed to diagnose a faulty relay.
That has to be the best and so well explained video on how a relay can be either bad or good. Thanks so much for your great explanation. Top class.
The diagram made easy to understand how a relay works. Thank you!
A relay tester.....This is the first video I've seen to bring this tool up into the discussion! Also very good explanation of how a relay works. A helpful and informative video! 👍
Thanks for explaining , showing, and testing the relay.
Sir, your presentation really illuminated me in the subject matter. Thank you
Very thorough and different ways testing the relay. Thank you 1A auto
You made so simple to understand dude. Thanks so much.
as usual... you videos are the BEST on the Internet!!! thank you!! :)
I knew their had to be a way to test those. The Chevrolet dealership and stupid autozone said they can't test them! BS! Thank you! You saved me 50 bucks! My issue is my more expensive radiator fans..... but that 50 will go towards them. Thank you again.
lol i like the horn drawing simulator
Excellent. Very details on hand on example on how circuit works on relay. Thanks.
Best auto repair video ever. Stumbled upon this trying to figure out why my Ford Focus high beams aren’t working but I hear a click! ✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️

Thanks for the info and all the great videos!
Great thanks. I'm curious about how they came up with those off the wall circuit numbers, but that is a riddle for another day.
Excellent video bro thanks a lot I have learnt it today and I hope am gonna work on my Van
Really good video. Both of my headlights went out. First thing I noticed was some corrosion on the battery clamps which I got rid of, and I made sure the fuses worked. I will be checking the relay after this. God I hope it's the relay, I do not want to deal with wiring harness. Also, do you think that a bad, maybe worn out battery clamp can cause the headlights to not turn on, even after car stars and all the other light work?
Very informative. Appreciate your time and dedication .🙏
Excellent job.
that showing very interesting I'm looking for that tool now you had in your hand there's a master one I'm trying to find thank you very much have a nice day

I'm 16 and I got a broken down 1994 F-150 4.9 I6 and I'm trying to fix it. This video helped me, thank you
Amazing video thank you!
Thank you sir.. appreciate your help..
hell yeah you helped me solve a gremlin in my headlights that ford dealership couldnt figure out.
Great job enjoy watching your videos😊
Here's some advice for fixing this for free. Yeah they're cheap but you may get stranded and need to fix it.
I had a ranger that sometimes wouldn't start. Everyone kept telling me it was a bad fuel pump. It worked fine on a cold start, but if I turned it off after it warmed up, and tried to start it back, the fuel pump wouldnt come on. I managed to find out that when the engine bay warmed up, the relay wasn't engaging. I did this by swapping the relay with something else and trying it. I then, being completely broke, cut open the top of my relay and saw one of the contacts near the coil of copper wire (electro magnet) was bent slightly away from the coil. I pushed it back straight, and taped up the relay housing good to keep dirt out of it, and bam. worked like a charm for the entire rest of the time I owned that truck and it cost me nothing. and if I'd listen to everyone else I'd have wasted time and money on replacing the fuel pump. The reason I didn't think it was the pump is because it was intermittent and only when the car had warmed up, and it never acted up while driving, only if I shut it off then tried to start it again.
Long story but I'm telling it so people know a relay can be intermittent. If you're not sure what to do, mark it with a sharpie (so you know which one is the original) and swap it with another relay and see if the problem follows or not.
EXCELLENT DESCRIBSION
I like that relay tester that you use that tells you if the relay is good or bad. Where do i buy that relay test tool?
Great video
Good explanation Mr how to test a relay
From the videos, I watched if you’re working on your ECM make sure your keys not in the ignition as it would start the car and you don’t want it to be and drive 7:00
You're knowledgeable and experienced,

Where do you get the relay test box and the other part , are do they come together in a kit ? Are maybe the name of it I looked for a picture on y'all website but didn't see . Your video is great especially the way you explain and break it down . You definitely would make a great teacher in some High school or Technical school . Thank, you for sharing and teaching some tricks of the tread.
Your are the best...... thanks.............
Thank you so much
What should I do if I have multiple relays that are good but still don't work it's on a 94 ranger if that helps I've tried everything and this was an awesome vid by the way👍👍

Great video explaining how to test relay ...may i please get the link info to order the type relay tester you used here in the video ?
Great vid my gmc sierra 2000 tries to turn on ... But it can't catch ... We changed the fuel pump ... What else could it be ? I'm guessing the relay? It's on old truck but still runs good when it runs
wow,, that horn works great
Just ordered a fuel pump and Rotors and brakes from 1A. Great prices.
