It is a 2015 leaf from portland OR and imported to British Columbia. The Daytime running light modification was done. To begin with the headlights worked fine and high beams also. 6 months later the left headlight seemed to stop. Checked the bulb visual and by switching left to right. Both work fine. By flashing the high beam on and off it worked again.....for a few months. Now it is not working properly . The lamp is on but only at 20% brightness. Checked all fuses. Oddly with lights on and then press the high beam control the right high beam goes on and the left headlamp dims to 0%. release the lever and the left light glows again to its 20%.
Any ideas???? Fuses? Is it the light switch control on the steering column? Or under the hood on driver side there is a black box "W6" that clicks whenever the light control is activated.
