I simply installed a hands free kit for my cell phone, didn't disturb and wiring harnesses, and after I'm done, no turn signals. Bulbs are good, fuse is good, flasher appears to be good becuse I put a generic one in and nothing changed. This is a 2001 Accord LX. Are they so fussy that you can't even remover the radio housing without causing a problem. Any help appreciated.

 

what did you plug into?

 

Plugged into one of the ignition fuses on the line side. Just forund the problem. Harzard switch is bad. Circuit goes through that switch first for what ever reason. Once I jumpered the ports on that switch, turn signals worked. Defective switch, in warranty.
