Learo2

Last week my battery died so I installed a new one. Now the following issues have come up. #1 the interior lights no longer work #2 the left rear turn signal and brake light no longer work. Everything worked fine before I changed the battery. I have checked all of the fuses and bulbs and they are all good. I have searching online for a week and can’t find anything. I can’t be the only person that this has happened to. Anybody have any thoughts? Thanks.
