The reason why I'm asking is because a failing 12V aux battery makes the car do all kinds of strange things electrically. If the battery is coming up on expiration and the fuses are good, then you should check the aux battery health.....

It's a 2014 REx
The car turns on and functions normally as it should. There a few LEDs that don't power on like the heated seat for the passenger seat only one LED lights up, some of the LEDs on the AC don't light up either.
Do you think that's connected to that issue? Where is the accessory battery located?
