I eventually had to trace the wiring and clean or replace all the
connectors to get the turn signals working on my B. Also check the ground
in the trunk; it's sort of in a bad location and may not be making good
contact. I believe the operational principle of the flasher unit is based
on resistance, so it's important to have the rest of the circuit in good
condition for proper function.
A few years later on the left blinker is starting to slow way down, so
it's probably a regular maintenance item.
