Fried Switches

[Golddeenoh]

i tested the fog lights in class today and their is only a maximum of 150 mA. since i didn't think it right to ask for another switch I installed a toggle switch, which worked until i had the head lights on, then it broke again... not sure what the hell i did but as far as i can tell the fog lights are wired into the correct places but still I brake it.

anyone got a schematic of the OEM fog light circuit for the 09 Yaris 3 door? maybe i can trace and ponder a solution.

The 09 fog light schematic is the same as the prior years, so you can grab it from the Yaris Files section of the Micro Image forum. The fog light switch only need to connect the two upper left wires together (the orange and yellow or white and yellow, depending on the package). When those wires are shorted together you are simply providing a path to ground for one side of the coil of the fog light relay (the other side of it has constant power).

The kit fog light switches failing is likely a failure of not the switch itself, but rather the circuit that bridges illumination and that switching to ground of the relay. On an OEM setup the illumination and switching occur via two separate circuits.

Was your toggle switch an illuminated one?
