My problem is a bit different. I bought the bell style turn signal switch. Left and right signals work normally and so does tail lights. I cut the original white wire going to the brake light switch and spliced in the signal switch white wire per a diagram I saw here for the bell style. I had no brake lights after that. Another source I found here says to splice in the tail light wire to the brake light switch. I have brake lights, but there is a malfunction.
Splicing in left tail light wire with brake lights on and left turn signal on will give no flash (solid on only) lights. The right turn signal with brake lights works as it should. This problem is vice versa if I splice in the right tail light wire. And sure enough, if I splice in both left and right, both tail lights will flash at the same time.
I do realize that a new part can be defective, but I do not want to guess and buy a new expensive turn signal switch, let alone the hassle of pulling the steering wheel and all the wires and reconnecting if it ends up not being the solution. Has anyone else had a similar malfunction?
