My breaker keeps tripping because of this wiring and/or faulty switches and now with a new switch, my ceiling fan won’t turn but the light still works and it still trips. I’m trying to figure out how to make this safe, because there is no way the current set up from the builders is correct. I have attached pictures for reference. Any help on how to fix this will be greatly appreciated. Currently, the left switch controls the bathroom lights and the right switch controls the vent fan. I’m assuming the ceiling fan in the bedroom is connected in somewhere as it stopped working when one switch was simply replaced.
