Nah, seriously, I agree with the above. Or your relay is zonked. Or it could be in the steering column itself. Have you tried pulling back on the signal tree to use the lane change lights to see if that lights em up? I actually had to do that everytime I had to turn for a while because basic turn signal wouldn't work.
