Hi, my 2008 v6 has one marker light working on the passenger side but the driver side is not working.. spliced in a new socket and new bulb.. still not working.
google question response indicated a possible bad ground.. i have no idea where the ground might be located. checked fuse box diagrams and nothing idicated
marker light fuse.. Any help would be greatly appreciated!!!!

 

I don’t like to be negative in my responses but since the replacement is not working either….

When trying to diagnose electrical problems one should always check to make sure there is power to where there should be, before throwing parts at the problem.

First, probe the positive side of the new bulb socket to check for power. You can do this either with a meter or you can make yourself a test light with your original socket by attaching a length of wire to both sides and installing a bulb. If you have long enough leads you can ground right back to the battery. If this test yields none, you will probe the wiring back through the harness until you have power, which will isolate where it’s been lost due to a poor connection or broken wire. If this test proves you have power at the socket, you can then check for continuity between the socket and ground. You can use a meter to check, going right back to the battery negative terminal with one of your leads. If you don’t have continuity at the socket, you will want check back through the wiring to find the point at which you isolate the break in the ground circuit.

Doing the above first establishes the issue, which will be either a power or ground fault, since replacing the socket (wasted time and money) did not cure the problem .
