03 Alero funky electrical issue

[schumld]

03 alero blower will shut off and the cruise light will come on. If I hit the cruise on/off and also the window switched then the blower will turn back on. If my windows wont roll down then I turn on the blower and cruise and the windows work again... similar with the cruise and turn signals... what gives here?

Sounds like a ground problem where circuits are backfeeding though other common circuits....need a schematic to find the common wires....
