Hi, I am Mike, welcome. I'm reviewing your question.
the turn indicators are fed from the very same wire that feeds the front turn signals, but I do see a splice for each near the breakout for the multi-function switch in the main harness. I would use a voltmeter and test there for voltage at splice S257 for the left urn and splice S244 for the right and turn the key to run and turn signal in the direction you are testing.
here is that wiring diagram,
The high beam indicator is most likely a separate problem unless of course the harness is damaged where both run, but here is that wiring diagram.
Check those wires as well between the instrument cluster high beam indicator and the lighting control module.
Did that answer your question? If so, kindly leave me a positive rating, so I get credit. After all, you have already made the deposit.If you don't, the deposit you made will just sit there and I won't get my share of it.
