How does the turn signal work on a Chevy Express van?

It comes out as dark green from the module but it turns to a yellow wire at the light. With the right turn signal turned on, does the front turn signal flash? If the front is flashing then you need to check the wiring at the BCM and see if it is sending the signal to the light in the rear.

Why is my turn signal not working on my GM Truck?

“No power coming out of BCM for turn signal-tested-found circuit 1334 yellow & black wire shorted to ground-found short located in underhood fuse block-replaced underhood fuse block.” My cost for repair: $600. However, a few weeks later, the left rear turn signal stopped working again. I took it back to the dealer.

Why does my left turn signal not flash?

What’s odd is the left signal will light up if I press the brake pedal, but signal won’t flash. So today I was checking a few things like the bulbs, fuses, and relays which all check out ok. After some futzing around with the turn signal lever, I can get the left signal to flash like it works normal but now the brake lamps flash with the blinker.
