[maine-iac]

hey all, i have some kinda wire demon in my truck, things arent going like they should. i just baught a fire/ice 15inch light bar for under my tailgate which plugs into my trailer plug and works fine when my truck lights are off, but when i turn on my trucks parking/headlights, both the passenger side blinker of my truck and the light bar stays on and doesnt blink, and when i turn off the parking/head lights the passenger blinker works fine. this is only a problem on the passenger side...WHY?! and my passenger factory foglight doesnt work, this is a seperate issue that hasnt work for a while. the fuse is good, someplace in the wire could be the problem to why is doesnt work? someone please help me, this is getting frustrating for me.

thanks everyone

It sounds like the parking lights wire is shorting out with the turn signal light wires. If you have a multimeter set it for continuity and, on the light bar side of the plug, check whatever connection is used for parking lights and each turn signal. If you have continuity, that's your problem.

It's possible the left rear lamp filaments are shorted together.
Simply replace the lamp, or swap it to the right side and see if the problem follows (still a bad lamp).

I would disconnect the line of fire and see if IT is the problem (being made in China and all).
