Recently had issue where my cars electrical started going crazy then my push start wouldn’t work long story short I had a lot of corrosion on my battery terminals so I replaced the connectors and jumped the battery and I got it going again but now it throwing a uo164 code and my blinkers aren’t working but Everything else is fine can it be my bcu?my hazards work just not the blinkers

 

Maybe check the fuses?

 

where would those fuses be under the driver side dash?
