No signal lights 2003

[elvis1]

Recently purchase a 2003 low miles viper. Drove for a little then wife pointed out no signal lights. Ordered multi switch and replaced, still nothing. Any ideas? Thanks

Wanted to add, hazards are working fine. Is there a fuse just for signals? I see a hazard fuse but no signal.

Hazard lights are powered at all times. Turn is only when the ignition is on. Looks like that power comes from the BCM.

They put a new battery in this vehicle prior to me getting it. I wonder if it did something to module. Can it be reset somehow?

Do the windows work correctly. That is the only BCM reset I know of.

Same fuse B13.

Do the dash signals flash left and right?
Both fronts and rears not flash?

The power to the turn signals go through the hazard switch fed to the combo flasher, fed from B13.

That multi function switch contains the combo flasher, hazard switch, dimmer and turn signal switch.

You need to measure voltages.

The dash flashes for hazards. Both front and rear lights flash with hazards. Nothing when signals are on. No dash or lights.

Can you check if the switch has continuity? Do you have a multimeter?
