2002 Eclipse Spyder

Question edited for clarity, 'fuse', unless you light it 'fuze'.Question moved to sub category.

If the radio has an inline fuse, it will be within 82 of the plug at the rear. They are built into the harness. Unlikely because there are three fuses covering audio.

Have you checked the fuse(s)? The owners manual, repair manual will show where they are located and which fuse goes to which device. You should also be able to up on Mitsubishi.com for added info.

First step would be to check for the fuses, has something else stopped working for example dome light?

Use a test light or voltmeter. The hot wire goes to the bulb tip. The other wires are grounds from the door switches and from the chassis. The chassis ground goes to the switch on the mirror. The other side of the switch goes to the bulb shell along with the wire from the door switches.

I know on the GTS the fuse panel is to the left of the steering wheel (drivers door opened). If you have the same model then the radio stations are also not visible. Look for the fuse with the picture of the lit cigarette on the diagram since they are on the same circuit. Should be a blue 15 fuse.

have you replaced the battery recently?

A bit of info....if you try to enter codes three times, you radio will go to lock...as far as I know, only a dealer can help you with that problem...

The Factory Codes are Usually "0000" or "1234"
