UPDATE: My dad and I spent several hours yesterday investigating the turn signal. We first unbolted the relay panel from under the dash and removed its back cover. There are five wires entering/exiting the combo flasher relay (Tridon EP-27). We found that by jumping across the yellow/red wire (presumably hot) to the purple wire in the center, the turn signal would function! Then we located the path of these terminals within the relay (i.E. On the circuit board) and soldered a jump wire across the two terminal connections. We found that the hazards and turn signals functioned correctly like this, and thought we had solved the problem. HOWEVER, we realized that this "solution" came with its own new problem: when the ignition is turned on, the relay would click constantly (without actually engaging the lamps). This noise is unacceptably annoying, so we had to remove our jump wire and are thus back to square one. I continue to stand by my argument with my dad that the relay is NOT the problem, since I already tried replacing it with a brand new one to no effect. So, I'm convinced that there is a continuity or power delivery issue between the turn signal switch and the relay. That is, we know the relay can actuate the turn signal lamps as it is supposed to, but something is not sending it the necessary power feed in order to do its job.
Two wiring diagrams are attached.
Thanks for further advice!
have the same problem?
