Passenger highlight and high beam does go on. New bulbs, okay and checked both work. Connector to bulb 3 prongs center prong goes to 0.1 ohm . Power prongs have 3 volts when the driver's headlight is turned on. Wiring harness seems to be okay because I get readings volts and ohms.

Power module defective?

Hello,

Okay, so what we are going to need to do here is a voltage drop test on the wires 1 and 3 from the headlight connector(1-white/dark blue and 2-white/dark green) to the Integrated Power Module. In the diagrams down below I have included a wiring diagram of your vehicle's Headlight Circuits, instructions on how to do a voltage drop test and the connector end view for the headlight and callout. Please go through these guides and get back to us with the voltage drop readings from these two wires, and we will go from there.

Thanks,
Alex
