I have a '89 CSX VNT which I got running so I can smog and register it here in Cali. The last thing to do is get the turn signals to work. I have checked all of the fuses and they are good. I have checked and replaced non working bulbs and put in a new flasher. When I turn on the power and click the turn signal, there is no blinking and the indicator isn't visible on the instrument cluster either. What am I missing.
