Have had my ’74 1.8L since new and this problem just started – the single turn signal indicator light does a steady flash, once every 5-6 seconds, for no (?) apparent reason, all by itself. The relay clicks and sounds as expected, but the turn signals aren’t on (they all work just fine) and the parking brake switch seems OK. Changed out the relay (3 times – the URO replacement), cleared up all turn signal connectors and replaced all signal bulbs. All fuses look good. This had been an intermittent situation for a few weeks, but now it’s all the time. Went away for 20 minutes when replaced the relay the second time, but came back. Seems like a square wave signal is getting sent to the flasher relay? Any clues as to what’s going on?
Thanks! |

As impossible as it might seem, it looks like it was the flasher relay, despite using/installing 3 other new ones (all URO). Removed/cleaned the parking brake switch just in case, but to no solution (but now nice and clean!). Installed a new Wehrle flasher that arrived yesterday and it's back working fine again. Will keep monitoring and take it out for a spin this weekend. Of course, the parking switch didn't look ANYTHING like the replacement parts though somewhat close to a Karmann or 412 door switch, but that's another thread...
