I am having a problem with the turn signals first the left wouldn't work now the right doesn't. Checked all the bulbs they all looked good and would work when swapped side to side. All the filaments come on properly including brake light which also the signal light but no blinking, left or right. So I thought I'd replace the turn signal relay and see if that worked but I don't know where it is.

The flasher should be under steering column support. You have one for the emergency flasher and one for the turn signal that look alike. Best way to identify which one is which, would be to turn on your emergency flasher and feel, or listen to which one is working. Of course, the other one is for the turn signal.

I found it. You have to remove a cover panel. It seems the actual cause of the intermitent problem was a bit of corosion built up in the electrical socket. I cleaned it up and appears to be working fine.
