heater blower not blowing

ive searched about this and it seems to be a pretty common problem. the blower itself works when you put direct power to it. but the switch doesnt control it anymore. i have 12v at the heater fuse, but nothing at the switch on the heater control. which means no power at the blower. so does anyone have some wiring diagrams for a 93 W250 heater setup. i need to find out where the 12v wire from the fuse goes and where its loosing power at !! thanks
