I have a 2001 Toyota 4Runner with 195k miles. Weather turned cold in Florida, blinker lights would work when I first turned the car on, then would go out - both inside and outside and all four. Hazard lights worked. Now, the blinkers will not even work intermittently. Hazards still work. Fuse for blinkers is good. Tried to replace the relay, but that caused the hazards to not work too, with blinkers out still. Replaced the old relay and hazards work again. Any ideas where to look next?
The hazards use a separate relay. listen for signal relay clicking to locate the correct relay. Consult your owners manual for fuse and relay layout.

It sure sounds like a short in the left signal circuit. I can't say where the wires are routed but you may have one with failed insulation or pinched under some hardware.
You could avoid repeated fuse replacement if you buy a cheap digital multimeter from Radio Shack (if you are in the US) or alternately, from an auto parts store. One adequate for this would be under $20 US.
Some have a continuity checker that sounds a 'chime' that stops when the resistance level rises a bit.
Since the meter could be damaged if the short clears, it would be smart to disconnect the negative side (ground) of the battery.
Putting the probes across the fuse contact will simulate the fuse for this checking but it will not let your signals function.
I would punch the probes into the fuse holder, put on the left turn signal and start removing bulbs and checking the routing of the wiring.
When the chime stops, you have found the culprit.

Relay or Flasher unit will be located in or near the fuse box,,,your owners manual will tell you where it is,, they are easy to replace, and cheap to buy.
SOURCE: hazard and blinkers went out at same time fuse is good
There'll be a unit under your dash near the steering column called the electronic flasher module that controls your blinkers and hazards. Sounds like the module broke

there are two flashers one for turning,one for the blinkers,and fuses to each, recheck them 4 totals
