Possible bad headlight light switch?
 

When ignition is on the interior lights blink every so often and the dimmer dosen't work.
When the ignition is off the dimmer works but the headlights don't come on. I switched relays with no luck.
Not having the dimmer working dosen't bother me but having the interior lights blinking does.
I suspect it's the switch but before I order one....
Any ideas?
