I've got a 97 4 Runner thats having electrical problems. The right turn signal burns steady when I apply the brakes. The same thing happens when I have the right turn on and I hit the brakes. I'm also having other intermittant lighting issues. I'm thinking that its a grounding issue. I'm not sure where the main grounding points are. Any help finding is greatly appreciated.

 

First remove your tail lamp bulbs and check the bases for meltage/shorting. Replace as required.

Do you have trailer wires? The converters tend to pack it in, and do funny things. Perhaps try removing it and re-checking stuff.

HTH.

 

It was the trailer lights!
