The turn signals on the 93 gave out the other day. I started hearing a humming/buzzing noise behind the intrument cluster when I put the turn signal on. Then that was the end of it. Neither turn signal works. Is there relay behind the dash? Or what else should I look for? Thanks, Bob Blake 90 V8 91 V8 92 V8 93 V8 93 V8 5 spd (with broken turn signals)
