I bought my Canadian 03 Pathfinder in S California at a great price, because it had issues with the problematic Daytime Running Light module.
Someone had already used a cutoff wheel to open my sealed module, and tried to repair the circuits. Didn't work, at least not when I bought the Pathfinder. It had one headlight, and one working daytime running light on the other side at night.
At the bottom of the circuit board, the pins are numbered. Using a schematic, I determined that jumping the following would effectively eliminate the function of the module.
Using 20 ga wire jumpers, I soldered the following locations together:
15 to 11
8 to 12
10 to 13
9 to 14
Stuff the modified module back into it's case, and tape it to prevent moisture. The daytime running lights are effectively bypassed, and now the headlights work perfectly. For those that need daytime lights, this can be reversed by simply plugging in a working running daytime light module.
