    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?

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! 😀

    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?
