I need help? The 2 back brake lights arent working. The reverse light on the passenger side isnt working. The light on the rear heater window switch isnt working. And head unit wont power up. I have removed the yellow connector and patched all wires together because the window washer pipe was soaking them. Any idea's peeps im stumped?? Thanks.

Have you checked the fuses and the bulbs ?

Yes I have already checked them they are fine
