    The left side signal on the hood and drivers door are working intermittently no corrosion at lights didn’t see any corrosion or chaffed areas was going to pin out the chassis node found the pin I need but the connector has no ground pin so if I’m not wrong that would mean it grounds through the module on another pin, any guiding hands out there thanks

    Check the hood harness over good for rubs or shorts to ground. I see alot of issues around the LH hood support/ bracket and where it wraps over and under the hood support bar near the bug screen.

    The hood harness to chassis harness connector is also common for moisture intrusion.
