Default Blinkers not working properly.

Alright so I have a 03 with 21000 miles on it. I have led tail lights and led front signal lights along with ACA housings and hids. I do have the hyperflash harness installed. Just recently I'll go to turn on the blinker and the arrow will be solid in either direction left or right. They occasionally work, sometimes they'll be off beat or work for a few seconds and then go solid again. Any ideas here? Very annoying!!

If I'm not mistaken the blinker stays green and solid when there's a bulb not working. Not 100% sure.

Ive already checked that. Every bulb is 100%. From what I know normally if you have a bulb out the blinker will flash faster than normal almost like a hyperflash.
Also wouldn't explain why it's happening on both sides.

the hyperflash harness i got off of radioflyer innov. Like 60$ only been installed for maybe 2 years with less than 1500 miles driven since. Are these prone to going bad?

The purpose of the harness and flasher was to "bypass" that part of the hazard switch that operated the signals (does nothing for the hazard function and in fact those will still hyperflash even with the hyperflash harness in place).

Probably an easy way to test would be to turn on the hazards and see if those stick or hyperflash. If they hyperflash and not stick, I would say the flasher element in the harness is bad.

alright first of all I really appreciate your replies. Second I tested the hazards. They don't hyperflash and they blink like they should no sticking.

problem fixed. The flasher unit on the hyperflash harness was trashed. Some Chinese crap. Replaced with an American made flasher unit. 14$ from my
local parts store.
