About a year ago the original system crapped out, so I replaced it with the solid state system. Only the middle blinker would work. So I read and found the emergency relay might be bad. I replaced that with a brand new one. Still only the middle turn signal works. Don't know where to look now.

Question did u replace all three boxes in the trunk,the two that hang and at the end pigtail small flasher box that's possible problem.

So, you replaced all the original analog pieces, with a new electronic box, and it still doesn't work? Have you gone through the 'thuntek' diagnostic process? I haven't seen any problem, that doesn't fit that process...

make sure your turn signal switch in your steering wheel is good too. I changed mine before I installed my sequential unit and it works great. It costs about $100 at WCCC.
