The car ran fine yesterday, this morning it won't start. The headlights work, the under dash lights work, but no radio, no heater fan, and no attempt to engage the starter. Turning the key does nothing....I checked the fuses in the fuse box as well as the two behind the diagnostic connector, all are good. It seems like an accessory circuit of some sort. My thoughts are............. solenoid?????? ANy suggestions appreciated!

 

Update......the single small wire that fastens to the solenoid was loose and dirty. Cleaned it and tightened it up and away it went!

 

Check your battery terminals. It sound like what happend to me and it ended up being the battery terminals.
