My interior and headlights come on but won’t start or do anything instrument panel or radio doesn’t even come on. I don’t have any power at the fuse panel under the hood fuse panel. The radio stayed on one day a drained the battery and has been not working since. Have replaced the correct battery and still nothing.

Hi,

On many of these, there is a battery disconnect switch/relay that can be reset. Power from the battery runs first to the under-hood fuse box. Check for this relay. If the battery failed, see if it will reset.

Let me know if this helps.

Take care,

Joe
