00979 - Lamp for Low Beam; Right (M31): Open or Short to Plus

[classexa]

Hi there. My right low beam bulb works intermittenly. Sometimes it turns on. Sometimes it doesn't. And sometimes it turns on, flickers and dies

I've this code:

00979 - Lamp for Low Beam; Right (M31): Open or Short to Plus

I've replaced the bulb. Swtiched the ballast from left to right. Also switched the headlight control module on the back of the headlight cover for the HID bulb. Nothing helps. Is this a wiring issue?

How do I check the wiring to the HID bulb the easiest? Resistance? Voltage? Which wires?
