'78 Honda Civic -- temperamental direction signals

My '78 Honda Civic (1200) has developed temperamental direction
signals, and I
am at a loss how to cure it. Sometimes they work normally, but then
stop. Then resume.
Then stop again. Completely unpredictably. It seems that sometimes
quickly flicking the signal lever back and forth would restore the
operation, but this may be an illusion. I think I've located the
switching mechanism in the console a bit to the left of the manual
choke knob. (This car has a manual choke!) With two fingers from
below, I can feel it vibrating when it works. Do I have to remove the
console to access the unit or can the repair be done from below? The
Honda repair manual has no suggestions.
Sometimes I have to open the window (at 20 degrees F) to give a manual
direction signal.
Thanks for any help with hints and/or referrals.

I remember changing the direction signal switch in a Pinto by
unplugging the old clicker and replacing it with a new one. It was
easily accessible.

Please give a few more details: Does it light the bulbs, but not flash
them, or just play dead? Do the four-way flashers work? Have you checked
the relays in the under-hood fuse box (if there is one)? Can't the Honda
dealer tell you where your relay is?

:-) In Canada, when somebody rolls down the window in and gives you the
'signal', it's called the Pierre Trudeau DIGITAL salute :-)

OP says he can feel it vibrating. To me sounds like the turn signal unit is
bad. It won't stick in one place long enough to do anything useful. Heating
element is probably too corroded to heat up properly.

I can't see something like this being particularly hard. It's easy to
remove under-dash trim, although clips might be brittle when the car is
almost 30 years old. And it's got to be roomier under the dash than in my
car, so peeking under there with a light should be possible.

In addition to the other posts regarding a potentially bad flasher relay,
you may also want to consider that the turn signal switch in the steering
column needs to be cleaned up especially since you state that flicking the
lever back and forth can sometimes get it to work. It's pretty easy to
remove the steering wheel to gain access to the switch. You may need to
lightly sand the electrical contacts in the switch with some 400 or 600 grit
sandpaper. I had a similar problem on my '88 Civic with the headlight
switch and cleaning it up fixed it and it's been working great for a couple
of years now.

At times, nothing happens. At other times, signals work OK for a while
but suddenly stop. At times, the light stops blinking but stays
lighted. The four-way flashers work OK.
