Here is my issue. I have the bulb out warning light that goes from off to faintly on while driving and then to on when braking. From reading around on the board sounds like it might be a grounding issue. The second part to this is my rear defroster does not work as well. Sometimes when braking the rear defroster indicating light will come on and the (best ever noise to hear happens) a relay makes that buzzing noise. Again from reading around on the buzzing noise this makes me think I one of the wires going to the relay making the noise is exposed. I have recently discovered that if I have the buzzing relay issue when staring the car with my foot on the brake. Then turn the card off then put the key in position II and press the defroster the lights in the instrument cluster faintly illuminate.
My questions are where should check for the grounding issue for the tail lights/defroster?
And I'm not completely sure as to the location of the relay for the defroster?
