2005 Ford escape right head light stays on after shut down. Checked switch, it's good. Pulled fuse it still stays on. What's going on?
First off you need to know how these thing's work , computer controlled . The SJB - smart junction box , a combination of fuse /relay & computer .
Do you know what DTC'S are ? SJB diagnostic trouble codes < not one's for the engine OBD 2 system . Need a factory or professional scanner to view these code's , Autozone , advance etc... can not read these code's .
Before replacing parts an taking the vehicle apart an checking wiring etc... Checking DTC'S should be the first step. So you know what diagnostic steps to use >
