Turn signal not working.

More than likely this is a switch issue, so we need to check the voltage at the bulb to find out if there is a signal when you turn it on.

Here is a guide that will help with this issue:

I am attaching the wiring diagram below which is what we need to use in order to check the voltage but here are a couple guides to help with this testing:

Once we confirm there is no voltage at the turn signal then we need to go back to the switch and see if the switch is sending it to the GEM. This means it is either the switch or the module so let's run through this info and let us know what you find.
