so far i'm having issues with my wiring. i have a 85 rx. when i bought the car, the guy didn't tell me that the wiring was melted on the combination swich. when asked about why the brake lights didn't work, he said the fuse is blown. i checked but they were fine. i replaced the burnt wiring, but still no brake or tail lights. the turn signals work and so does the rev. lights. could it be the comb. switch? or the brake switch? please help.
