Toyota Matrix starts after boost but all lights not working, possible fuse issue on Toyota Matrix

Some Toyota Matrix owners report experiencing issues where the vehicle starts after a boost but all lights are not working, potentially indicating a fuse problem. These owners often find it necessary to check the two main fuse box locations—one beneath the dashboard and another under the hood—as each controls different functionalities, including interior lights. Additionally, some owners discover that poor electrical connections between the battery and the fuse box can lead to electrical system failures, resulting in non-functional lights. It is also common for owners to consult interactive fuse box and relay diagrams to identify blown fuses, as these can cause both starting failures and lighting issues. Furthermore, low voltage readings on the fuses, such as around 4.5 volts, may suggest ground issues or problems with the main fuse. Other potential causes for starting failures that affect light functionality include starter relay and ignition issues. Therefore, thorough checks of the fuse box, connections, and voltage levels are recommended for effective diagnosis and resolution of these problems.
