Is there a fuse for turn signals? Was looking at fuses in owners manual and I dont see them listed…..where does the power come from?

Might help to know what vehicle you have.

From the BCM which also does the flashing and brakes. That's right; no flasher module and the brake pedal switch is really a sensor. No dedicated fuse, one of the BCM fuses in the underhood box supplies power to the BCM to use. The BCM itself is powered from the big fuse near the battery.

ahhh, I suspected BCM must control it. Thanks

A scan tool will show the inputs and outputs which you can see the turn signal input and if it's not responding to your hitting the lever you know you have a problem between the switch and the BCM.
