Turn Signal Troubleshoot
Had this '99 Tacoma since '99. Here are the symptoms, in the order I noticed them. This began about one month ago out of the blue - not right after anything, and long after anything electrical was touched:
I think the symptoms point to the $100+ switch being worn out, but if anyone could confirm or suggest a better test technique, I'd like to know before I waste any more money.
- Left turn signal dashboard-indicator light sometimes doesn't light. This happens intermittently, but increasingly.
- Left turn signal exterior lights (both) do not light when the indicator does not light.
- Fuses, both behind dash and under hood, are good.
- Bulbs and sockets look fine, clean, and dry, both left and right sides.
- All four signals always flash normally whenever the hazard switch is pressed.
- Checked combo headlight/signal switch pins 1-2 with meter and continuity looked fine, but this exercise seemed pointless because the problem is intermittent.
- Replaced the flasher relay without testing it first. That didn't help. Murphy's Law.
- With the switch in either left or right position, I can hear the flasher clicking normally whether the signals are lit or not.
- The signal flash rate is about 92 flashes per minute, on either side.
- If I gently press forward just so while pressing down on the switch stem, the left turn signals (and indicators) will work properly, although sometimes it takes a few tries.
I think the symptoms point to the $100+ switch being worn out, but if anyone could confirm or suggest a better test technique, I'd like to know before I waste any more money.

On the other hand, love the screen name! Have watched every episode numerous times over the years.

It's my dog's name (see likeness in my profile) - given because ever since a puppy he swims not with his head held low but way up out of the water, much like Cleese's head protruding above that suit. Ditto on re-runs - that one, and Lucy.
