Should all fuses make test light light up in ON position?

Yeah, it’s a electrical problem and I don’t know much in that. Let me explain the issue.

Out of the blue one day (which, I know things usually don’t happen like that, well I did replace my windshield but don’t see how they could have caused issue) when I hit my brakes, my parking light and interior night lights come on. Release the brake they go off. On the other hand, when I do turn my parking and interior night dash lights on, they come on as normal, and my cruise control will not set and the ESC OFF light will come up after about 5 mins of driving and not work until car is restarted. As if it thinks the brake is engaged when the lights are on? Also, my remote start doesn’t work anymore, starts up but the it turns back off after dash light flashing which probably just means the current issue is affecting the remote starter and that cannot operate properly.

Now I have no clue what to do. Since this is a beaterish car I kinda wanna learn and fix it myself but at the same time I have no clue where to start, so I did with the fuses.

Some say it could be a bad ground and I know how to check the grounds voltage and know if it’s bad, but how do I start knowing which ground could be bad or where are all the grounds in the car?

Haha, so yeah, if you have any idea or pointers I greatly appreciate!!
