Basically I noticed that because on my stereo back up camera stop working. Before the cops will pull me over, I'd like to fix that issue.
I checked the fuses, but they seem to be ok.
I spoke with the guy who knows the electrical, he suggest that the shifting module on transmission might give that problems. (See picture).
I wonder what gurus would say.

Check power coming in and power going out of the suspected device... Then work your way uphill or downhill accordingly.

 

Agreed. Start testing.

 

Check fuses, sockets, bulbs, trace the lt grn & blk wires with a PowerProbe

 

I wonder where I could get the wiring diagram for those lights..?

i gave up, brought it to car electrician... cool russian dude, charged me 100$, but find the problem... apparently one of the pin in main fuse box was crooked... can you believe?!

 

yeah that fuse box can be tricky to reconnect properly
