Lost wipers,Power Seats,radio, Power windows

On the way to work today I suddenly lost all power to the radio, onboard computer, power seats, and power windows. No fuses are blown and none of the relays are labeled so I have no idea what relay is for what. The Car is a 1990 525i. Please Help :frown:

there's a fusible link on the right hand side shock tower it will be right off the positive side of the battery.ours had a hairline crack in it everytime we hit a bad bump we would lose power just like you did .a new one cost us $35.00 it has been improved over the old style.I installed it and we have not had anymore problems
