The fuse is ok. We have replaced the relay with a known good one. We have replaced the steering column switch (twice) with know good ones. Problem still persists: Turn signals do not work at all. Emergency flasher does work ok.
Suggestions?
Thanks

Check the black-white-green wire at the turn signal switch for power

Dear Rasmataz,
Thank you for the lead re the wire for the switch, and sending along the wiring diagram. Barry & I continue to work on the problem (it's actually my car). We found the green/black/white wire and built a little tool to remove it from its harness. We inspected the wire and found no problem with it, nor the harness. We brought a second switch unit and tried the harness in that unit, but the blinker still didn't function. When we put the harness back in the original housing in the steering column, though, we can get it to function properly (intermittently) by pulling all of the harness wires toward whoever's sitting in the seat. This worked better when we detached some tape holding that bundle of wires to other bundles of wires, but it's not a fix of the problem, and we still can't figure out what the problem actually is. Any suggestions would be appreciated, or tips on further troubleshooting. We assume now that it is not the switching unit, but cannot identify a problem in the harness. One option is to cut and splice all of the wires into a new harness, but we would rather save that option last.
Many thanks,
Tad
