When you say you checked all of the fuses, did you actually check them all or just one the ones that said they were for the signals? Check every single fuse there is to check in both fuse boxes, the one by the drivers door in the side of the dash as well as the one under the hood on the drivers side if you haven't already. GM piggy backed many circuits upon each other and often times will blow an unrelated fuse due to a different labeling!
If you do that and still nothing, then I'd find the relay and see if that's messed up, then look at the signal switch in the steering column!
