Looking to learn new things about m car and teach others..

Hey.. i connected a 12 v day time running lights to both my car headlights about a month ago.. they were working just fine until yesterday they randomly went out.. (both headlight and DRLs). After a couple minutes checking all the fuses, i found two fuses which are blown (15 amps). after checking the owners manual, I've came to conclusion that they are connected to the highlights.

I replaced the fuses with another 15 amp fuse and when i turned on the lights (engine was off). They suddenly went out, i replaced them once again and took off the DRLs and they went once again.. is it possible this might be a short circuit, or the switch is burnt out?

Sounds like a short. It'll either be in the wiring or at the switch. Switch would probably be the easiest to test. Test for resistance with switch removed. Of it reads 0 resistance with switch in both positions it's the switch. If after replacing after gain the issue occurs again it's most likely bad wiring.

I do this from my phone. Do the BSD. Powered by Mazda 2.5l. Zoom-zoom 😎
