Hey all. Looking for some advice/technical expertise.

2021 Bronco Sport Badlands.

So, about a week ago, my passenger side turn signal started making the "quick click" noise. In some of my other vehicles, this always meant there was a bulb issue. So, after checking, my rear turn signal was out. I went and bought some bulbs, swapped them out, but the problem didn't go away. I swapped the entire module from the passenger side to the driver side, and the turn light worked as it should. I checked the one from the driver side when it was connected to the passenger side, and the bulb did not light up. Actually, when I say didn't light up, that's not exactly true - it lights for a split second and then nothing. Same thing happens when I put the hazards on. At a loss here as I suppose it may be wiring.

Fast forward to yesterday, now the driver's side is fast clicking, too, but it's the driver side brake light instead of the left blinker.

Took it to the local O'Reilly's and had them do an OBD scan which returned absolutely nothing.

Anybody seen/heard of this? I'd rather not take it to the dealer if I don't have to. Any help or direction would be very much appreciated.

that would drive me crazy for sure. i'd say put on your hazards and have someone sit in the car and brake on and off as you wander around the car and check every light to make sure they all are working. something must be out. odd that you're not getting a code, as most bulbs are monitored, but oddball things happen.

My turn signal was clicking fast. Much to my surprise, it turned out to be both of my red stop lights were burned out. They were replace free by the dealer under warranty and the problem was fixed.
