After spinning out in a snowstorm the turn signals and brake lights stopped working

Hello, I'm Danny.

It sounds like you might be having an issue with the light control module. I've attached a picture below of its location and circled in red.Hope this helps and thanks for using 2CarPros.

actually has a brand new one..

The LCM houses the flasher on that car as well as other lighting functions. You say all the brake lights are out as well, including the high mounted light? How about the cornering lights? Fuse 5 powers the turn signals and brake lights. I would start there using a test light connected to ground to be sure that fuse has power to both sides. If it does then you will need to see if there is power at the brake light switch on the Light Green wire with a Red stripe. That is the power feed to the brake lights and the turn signals, but they split just before they get to the brake light switch, If you don't have power there the wire is broken between the fuse box and the splice for those wires. The same test light connected to ground should light if touched to that wire in the brake light switch connector. I'm thinking it won't light. If it did at least the high mounted brake lights would work as they are direct wired from the switch. To see if a lack of power on that line is the problem you could make a fused jumper lead with a 15 amp fuse in it. Connect it to battery positive and touch it to the connector with the light green wire with red stripe. This would back feed the circuit and if the turn signals now work it's a broken wire or damaged fuse panel. The wiring for those circuits is attached. Fuse 5 powers the lights that are out so I would start there, it may be the fuse is bad or the socket it is in went bad.
