turn signal and hazards not working

[dlud]

I have a 2002 base. The right blinker wasn't working (I think it was due to a loose bulb) and while I was tracking that problem down the left side quit working. The hazards still worked on the left side and both rear and then all blinkers and hazards quit working.

I checked the fuse (good). Tried a different turn signal/hazard relay (no difference). I pulled the hazard switch and replaced that (no difference). Pulled the headlights out and cleaned the contacts (no difference). Even tried another set of headlights from my 2000 S (no difference).

I pulled the turn signal/windshield wiper/cruise stalk and replaced that (no difference).

I am now at a dead end as far as ideas.

Anyone have any suggestions?
