The low beam headlight on the passenger side of a friend's 2011 Venza does not illuminate when the headlights are set to "auto" on the turn signal lever. When switched manually to "on", the bulb works. It's a Canadian built model that uses 9005 halogen bulbs. As the bulb works when manually turned "on" it's not the bulb or a fuse. It wouldn't be the sensor ("that recognizes a lack of sunlight") because the driver side bulb works on "auto". Has anybody experienced a similar problem or knows if there would be separate relays from the sensor to each bulb. There is a main junction block 827200T011 associated with the engine fuse panel that supposedly controls the function of the lights. It's a US$200+ part so unless I can accurately diagnose that this is the problem, I'm not willing to just blindly change parts. Any input would be greatly appreciated. Thanks
