It started with the turn signals I change the fuse for the turn signals three times within 2 days. Then all of sudden the hazards and turn signals weren't working but the fuse was fine. I tried looking stuff up on the internet at that moment and seemed mentioning of I believe it's called the hazard relay but it's under the dash directly above the OBD2 hook up. So I unplugged it, took it off took it into AutoZone to see if they had a new part and I was just going to buy a brand new relay to to replace it. But they didn't have one so I took the old one back out plug it back up and all of a sudden the flashers and turn signals are working again. So now here's where my issue lies I was driving and next thing I know my turn signals don't work my hazards do work my windows don't roll down my windshield wipers don't work my speedometer don't work, but my headlights including the dimmer deal work as well as the taillights work, radio works, rear defroster doesn't work my dome lights don't work. I was checking the fuse panel underneath the hood and had a guy at AutoZone helping me, he said it wasn't the relay to his knowledge and once he said that the relays were good I just knew that I was going to have to chase down some wires so my question is if you have ever had this problem or know somebody that had this exact problem what roundabout areas did they find it the issues or the source of the problem from.
This may sound crazy but I had the same issue. Turns out the cigarette lighter adapter for USB charging was bad. I went through wiring and fuses nothing helped until I unplugged my USB adapter then everything started working properly. Got a new adapter and everything still works
