Hello. I have a 2017 Bolt. Both of the front turn signals went out at the same time. I checked the bulbs and they are fine. I would like to see the fuse/relay/flasher, but I haven't been able to figure out which fuse or relay to check. I have checked about half of the fuses now, but thought maybe you would know where to check.

There is a real possibility of the wire being chewed by a rabbit or rodent, but haven't seen any obvious signs of that yet.

Thoughts?

Welcome to the forum. I gather that they don't work when you activate your hazard lights?

Believe the front left/right turn signals come from the body control module number 7 which is on fuse 43 inside the car.

Thanks! I love my bolt. You are correct in that they don't turn on with hazard lights. The rear turn signals all work fine. I just checked fuse 43 (and all the bcm fuses just to see) and they all appear fine. I guess I need to put it on the lift and find the wiring. At this point I'm assuming it is a chewed wire.

From what I can see, there is no flasher like vehicle's would have in years past. If it were me, I'd start my disconnecting the 12v battery and letting things "reset" before moving on to the more difficult possibilities.

Thanks. That's a good idea.

Brooksbl, did you figure this problem out? I am experiencing the exact same issue (no front blinker on either side). I checked all the bcm fuses (all are good) and also disconnected the 12v battery (didn’t fix it).
Thanks!

An update on this - a mouse chewed through the front turn signal/temp sensor wiring harness on my '21 bolt. The harness is wrapped in an anti-rodent tape, but the rodents found a spot that wasn't wrapped completely. After I took off the front bumper cover, I was able to solder the wires back together, replaced the BCM7 fuse in position 43 on the interior fuse box (next to the driver's left knee). This fixed the problem. The only hiccup was that the temperature sensor read "-40 F" for about 10 minutes after the repair was complete, then it went back to normal. I'm guessing it takes a rolling average of temperature, so it was reading -40F because it was disconnected for a while.

Anyone else had mouse issues on their bolts? do you have any good recommendations for rodent deterrents?

What is the fuse number for the right turn signal in the fuse box on the Bolt ev 2019?"

What is the fuse number for the turn right flasher in the fuse box on the Bolt ev 2019?
