hey how are you

1- have you tried unplug headlight switch ?

do below test and lets see what circuit is draining battery

Battery Drainage Test

1- Voltmeter
2- settings on voltmeter will be on milli amps.
3- go across all the fuses in the car and see which one is reading higher than 0.3 to 0.5 milli amps
4- the fuse drawing more than 0.5 miili amps ,will be the suspected circuit that needs inspection for the drainage.

you will need a factory scanner or equivalent to run a diagnostic scan & retrieve fault codes from the all the modules in the vehicle.
can you get that done and post the results back here and we can continue trouble shooting, the scan will narrow it down for us .

Please let me know

Thank You
