My left rear turning signal is intermittent I believe it's a wiring issue since I changed the bulbs and the control module. Does someone on the forum have the wiring schematics (colour coding) that can help me identify which coloured wires in the wiring harness in the trunk that controls the left rear (driver side) turn signal?

Signal from Footwell Module is BL/GN, Ground is BR

Thanks for the information. Do those coloured wires control only the left or both left and right?

Left, although several of the grounds are the same color on the diagram.

Is there a link for the diagram? Would come in handy for the future.

Thank you once again for your help!
