Hi - Dave here -, contributing to RepairPal and providing expert advice since 2010. There is no easy way to know what is going on - but I would start by testing the battery to ensure it is "good" and can sustain a load. Then check the charging system - if you have a known good battery - to assess if the battery can sustain enough needed voltage. Many times a lack of power can prevent desired accessories in the vehicle from working properly. This is by far the most obvious possible result. https://repairpal.com/auto-repair-near-me Click the link to find some shops near you who can help out!
