Following my wife in her 98 GT last weekend, driver rear turn signal was flashing really fast. I figured that was a bad front bulb. By the time she got home, however, no turn signals either side worked. The emergency flashers work, I swapped the flasher relay from my car and it works in mine but not hers, and the #5 15A fuse is good. I just bought a new turn signal switch, but before I tear into the steering column to swap it out, anybody have any other suggestions?
