I have a 2007 Volkswagen Jetta and I have a problem with my blinkers.

All the wiring connectors look to me in good shape, none are bent or broke, also I’ve replaced the combination switch twice now, is there a ground some where I’m over looking? All my fuses look good as does the flasher. For the life of me I can’t find a blinker relay although it sounds like it’s behind the dash some where. Could the steering electronic control module be the problem? Some one please help.
