Thank you all for your rewplies and the link., I actually tested the bulbs, which are good, but not working, neither is that small bulb under the headlight. The whole circuit appears to be dead, but the wires all tested good. I found no shorts. For some reason, the tailight works when the ignition is in park, but it does not work when the ignitiotn is in the run position. I am pulling outy my arempit hair since there is none on my head. any pointers?
