Left hand side indicators not working, i have done a lot of searching, but still cant work this out, i only got the car a week ago, and have been busy with high idle, now that is sorted, i'm working may way through problems as i find them, I have continuity from the yellow/slate wire in the connector block just under the left front vent, to the lcm connector with yellow/slate wire, any trouble shooting tips would be much appreciated.

The Yellow / Slate wire is ground seeking provided by the BPM . Do you have that blinking ground as you do the left turn lever ?
Fuse # 8 / 10 amp Left Heelboard Fuse Box . I think the original size was a 5 amp but they uprated it .
Separate fuse for the right turn signal
Do you have the fault with left Fwd and left Aft and left repeater , all 3 ?

The dash arrows indicate that the lever switch works .
You would read the blinking ground provided by the BCM at the LCM connector by looking with a needle meter on the resistance scale.
The dash arrows are tied into the Yellow / Slate wire between the BCM on the LCM so that would point to the LCM or wiring to the bulbs .
Have You tinkered with the bulbs or cleaned the sockets ?
Those under car sockets get corroded

Hi Mark - did you find bad solder spots on the BPM board?
Just curious as I was looking at pictures of some other manufacturers BPMs and ECMS having bad solder joints.
These "bad" spots seemed extremely hard to detect due to the joint being so small as well as not appearing bad to an inexperienced layman like me.
The common fault / bad joint on our ABS board looks easier to detect because it's larger and more obvious.

Left turn signal on wires 1996 x300 still not working, trying to make sure I understand this, if I've checked and the fuse under the heal board is good... and the turn signal bulbs are good I'm left with an issue with BCM or LCM? The light control module is located where in which fuse box? How will i know what to look for? The Body Processor Module is behind glove box. assume if i get up under there i can see it w/o taking glove box out? Also not sure what it looks like... Mark was speaking of finding bad solder joints, assume these modules are easy to open and check for that? Which module should i check first?
I've assumed if all three bulbs are not working/blinking its likely not a wiring issue does this mean the culprit is either the BCP or LCM?

Mark did you have to repair both the LCM and the BPM? As a novice I’m not sure exactly what I’m looking for and my late 50’s eyes not so good at seeing those super tiny solder joints... am I correct that all you did was resolder a few breaks? Am I looking at the top or underside of the circuit board or both... any advice how to proceed appreciated.
