Help troubleshooting LED mirror turn signal

[JudgeM]

Happy new year to all. Hope you had a good start to the New year.

I spent my new year day trying to troubleshoot my LED turn signal on my mirror.
I previously mentioned I had this problem and I thought I may have to open the mirror up and was NOT looking forward to that.

So I took the door card off and saw there are 2 connections for the mirror, one is the motor and the other was for the LED turn signals. I removed the connector and used 12Volts to power the LEDs directly. They lit up.

So the problem is not the LEDs on the mirror. Its the factory wiring.
Can anyone help me trace the connection and give me some advice on how to trouble shoot this ?

I should add that the passenger side one is working fine its just the driver side.

I have attached pictures of the connection. The said connector is shown in the top right. It has green and white/black wire

your help is much appreciated.
