I have a headlight on one side of the vehicle out. Checked the bulb and it wasn't that. Checked the fuses and wasn't that either. So am thinking its a problem with the connector or the wiring. No obvious signs of melting/broken wires but am wondering what the best way to resolve the issue is.

If I get a meter on the connector and am not getting voltage - what should I do to diagnose problem or resolve. I'm thinking cutting off connector and say 3 inches back and seeing if I get voltage and then if I do then resoldering a new connector on, if I don't work back another few inches but that seems very trial/error.

Is there any other better way of diagnosing the problem ?

Suggestions...

 

I wouldn't start cutting just yet. may want to try following the diagram and check for voltage at each subsequent connection going back from the bulb connector to the fuse. may just be a loose connection or corrosion. just my 2 cents.


go here for the 2005 diagram (good for 2005-2007). https://www.scionlife.com/forums/sci...estion-233115/


Also there is the 2007-2010 diagrams. good luck.
