I have a 1998 A4 2.8 v6. and the turn signals stopped working. I replaced the fuse but there still dead.

Anyone have any suggests on fixing it myself?

Also the brake light is blinking and the ABS light is on. In the manual it says that the ABS isn't working. I took it to the dealer and they said it was fine but the light came back on. Is there some way I can clear it?

Thanks
