To check electrical problems in a 2004 Scion xA, start by inspecting the battery and its connections for corrosion or loose terminals. Use a multimeter to test the voltage and continuity of fuses and relays in the fuse box. Additionally, check wiring harnesses for any visible damage or wear, and consider using an OBD-II scanner to read any trouble codes from the vehicle's computer system that may indicate specific issues. If problems persist, consulting a professional mechanic is advisable.
