Turn signals failed?

So today I was driving to school when i noticed the left turn signal blinking erratically. I couldnt tell if this was just glare or the signal but it went away.

So later in the evening it happens again and I can tell its the signal. I try hitting the left and right arm but no good. When I touch the hazards it goes away. Then I hit a bump in the road and it comes back and I hit the hazards again and it goes away. Now my turn signals won't work. I can hear it click but no lights. Any ideas on where to begin or what could cause this? Thanks!

when you say erracticly do you just mean flashing fast (which once again would be the CPU indicating a bulb failure or short) or do you really mean erracticly as in no pattern (which would indicate a CPU failure and the CPU's flasher board would need to be replaced.

And I do have rebuilt CPU flasher boards available on my website

Thanks for giving your input on this one.

I mean like really erratically as in like left then right or both together blinking in different variations of fast.

Where is the CPU located? You don't think it could be some wiring short in the actual gauge consoles wiring or is this commonly associated with what you named? Thanks again.

well again. if you have a bad bulb then the side with the bad bulb would be flashing faster than the side without the bad bulb.

the CPU is the black box next to the fuse box in the driver's kick panel

No they were flashing without me touching any controls that have to do with them. Im pretty familiar with how the bad bulb flash is and this was a bit different.

do the hazards work ok or are they messed up too (they use the same circuit in the CPU)

No, it is the CPU flasher board that needs replacing- I have rebuilt ones available on my webstore/website
