Hello, I am having a bad time trying to figure out this turn signal deal. I have right turn signal but no left. I checked all the fuses, and relays. I even brought it to loves shop( no help) they couldn't figure it out either. I have lights on the left side but not a turn signal nor 4 ways. It's a 2008 kenworth w900. Any information would be a big help. Thank you.
Its 2022. Doesn’t matter anymore. Just cut over on people. But really it sounds like the switch it self on the steering column
Did they test your flasher relay ? Or it's possible the signal wire for your left turn signal has a issue (broken or bad connection)
