This dash idiot light is coming on and off periodically. When it is on, I cannot locate any "out" lamps; head, stop, etc. Thoughts?

 

check the tail lights thats usally where its at bulb maybe loose

 

You need to check all 3 bulbs in the tail lights. Look at the contact wires on bottom of the bulb. Sometimes the get hot and kind of melt into the plastic I have had it happen twice in 2 years. It will give you the exact problem you desribed. I have now replaced my bulbs with a bulb that has a glass bottom. That way the wires can't melt into the plastic.

 

Thanks, all. I found a bum bulb in the right rear break light.

 

And just think if you hadn't made a post here you would gone to the dealer to hav ethem trouble shoot it at $80 and hour and then charge you for 1.5 hours labor and $3 for the bulb
