My 1970 Culass turning signals are out of sorts. I first noticed them beginning to blink very slowly. I bought a new flasher, but now the left signal doesn't work at all. I've checked all the bulbs, and noticed the one on the rear left is loose in the socket. I put in new bulb & bulb grease. The right signal is working ok, but left just doesn't want to work. Does anyone have ideas of how to fix?

 

Do the 4 ways work?

 

Did you replace the hazard flasher that is plugged into the fuse box or did you replace the turn signal flasher that is plugged into a socket on top of the steering column?

 

If the right signal is working its not the flasher.

 

Just pointing out that there are two flashers for the different functions.

Have a look at this thread for info on loose bulb connections:
