1. Double-check the fuses. Sometimes fuses can blow without looking visibly damaged. Try using a multimeter to test the continuity of the fuses related to the dash lights.
2. Check the wiring. Ensure the wiring is properly connected when installing the stereo. Look for any loose connections or damaged wires that may affect the dash lights.
3. Inspect the dash light bulbs. The dash light bulbs may have burned out or become loose during the stereo installation. Try replacing the bulbs and ensuring they are securely in place.
4. Check the dimmer switch. The dimmer switch controls the brightness of the dash lights. Ensure the dimmer switch is turned on and set to a visible brightness level.
5. Look for any grounding issues. Ensure all the grounding wires are properly connected during the stereo installation.
6. Reset the car's electrical system. Sometimes, disconnecting the car battery for a few minutes and then reconnecting it can reset the electrical system and resolve any issues.
If the dash lights still don't work after following these steps, seek help from a professional mechanic or auto electrician for further diagnosis and repair.
