Right ive got a few niggling problems with my Saff Cossie, and wondered if any of you good people could help

1. The past few days the ABS light has been on the car constantly, but started being more intermittent, however yesterday the car totally lost its brakes and pedal went rock solid, i had to miss the junction i was due to turn into as it wouldnt stop , once car was turned off and started again, they were fine

2. The electric window switch keeps blowing its fuse, any ideas why? and they go when your not using the windows
