ABS Light and Signal Problems on 99 cavi

I have a 99 cavalier and my ABS light came on and at the same time my signals did'nt work so I turned off the car and turned it back on and everything was fine, and it was until the next day. I unhooked the battery and filled my brake fluid and started it back up but it took about 10 times before the abs light went away and my signals worked again.

could someone please help.

thanks
