Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
do the turn signal green lights light up in the dash when you go right oor left with the turn signals.and no front or rear turn signals will work at all ?
did this problem happen out of the blue one day ?
nothing was done to where now you have this problem ?
brake lights work fine ?
ok since like you said the hazards and the rear brake lights work fine as they share the same wires and power from the BCM this issue will come down to a bad turn signal switch or the BCM being bad
make sure all the fuses are good if they are then a scan tool need to be connected to the truck and see if with the scan tool you can active the turn signals with the scan tool if you can then the switch is bad of you can NOT then the BCM is bad and will need to be replaced i am sorry to say
