Turn signal failing

[CorollaKen]

My left turn indicator is not working (flasher unit under dash, behind glovebox).
It works sometimes, but most of the time it doesn't.
Right turn and 4-ways work fine.

I replaced the original Flasher module back about 2-3 years ago with an $85 CDN OEM/Toyota module. It worked fine until about 2 weeks ago. So I bought an aftermarket one, "TRIDON" I think, for $15 CDN. I finally got around to replacing it today - it fit, worked left-right-4way, so I closed up the dash, and sure enough, went out a few hours later and sh!t, left turn stopped working again

All bulbs are fine too.

How to I trouble shoot this one ? Is there wiring going bad ? Has anyone had this problem before ?

Thanks,
Ken

PS Yeah, left turn indicator isn't working...is working....isn't working,,,,is working..hahaha

check your switch thingy, the contacts in that might be wearing low, if you can find a junker try and get that pice out of it and see.

Well, I fixed the darn thing !

Here's the long story....

I started under the dash at the signal relay and proptly gave up following all the wires

I then took the lower dash off under the steering wheel.

The three clusters of wires (one being the big thick yellow airbag) 2 of which go into a multi-contact connector, looked easy to poke at. I started from left to right and while the left blinker was working, I just touched each wire, sure enough, I touched the 3rd or 4th wire and the blinker stopped. I pulled it up and the blinker started again, pushed it deeper into the connector and it stopped. I pulled the wire down harder and it came out of the steering column - cleanly broken wire. Whoo Hoo. So I fished out the other end and slpiced them together. Voila - fixed !

Cheers,
