I started the car yesterday, and got out right away. I noticed it was no longer running (it did start though). Since then everything seems dead, with the exception of the horn and 4-way flashers. Nothing else works, including headlights, radio, door locks, power windows, dome light, etc... When putting in the key and turning, there are no clicks, no sounds, no lights, nothing. It is not the battery though, because the 4-way flashers and horn work fine. Any ideas what the problem could be? Thanks!
