What the rear has to do with the front passenger light and which one or which side?Check the ground in the REAR taillight. I had the same problem. Was gonna replace everything in the front. the brown wire in the rear tail light was a little corroded. cleaned it up and plugged it in and it was GTG
Sounds strange ,HUH?
The way the system is designed,they are all interconnected. pull off the rear covers on the taillights like you are changing a bulb. look for a brown wire,which is the ground. pull it out and look at it and the reinstall it and turn on your headlights and wiggle the ground and see what happens.What the rear has to do with the front passenger light and which one or which side?
