speedo?

I have a ford cougar 2.5 V6 1998,the speedo suddenly stopped working and my traction control warning light now stays on,although it is not clocking up any miles on the odometer ,i would much rather have the speedo working as it should.i have checked the fuses but they all seem ok ,any ideas as to why it won't work.

ps . it does flicker into life on the odd occasion ,but only for about 2 seconds ,then it's gone again.
