You could try and clean your existing mode selector switch:

Probably cheaper than buying a new one. Just to be sure, check the transmission fluid level first to make sure there is enough in there as low fluid level could contribute to the hard shifting (but not the selector lights being out).

Also, I'm with the others; don't think the turn signals not working is related to the hard shifting. Must be just a coincidence. Do the marker lights come on at all? Maybe your blinker is just blown?
