I have a 1981 300D. On a recent road trip I had to run my hazards for an extended period of time while in the mountains (why I had to have them on is another story: throttle pivot mount failure - argh!). Anyway, at some point, the flashers just quit. Now I have no turn signals. I checked the fuses, and they're fine; I also checked the light bulbs - all are okay. Could the hazard have blown out a relay somewhere? If so, where, and how would I know if that's the problem? Any other ideas? Thanks! Mike
