Power windows mirrors locks not working

Power windows power locks and mirrors don't work at all none of them. I can't find fuse link nor a assy power fuse on this car. I have checked the fuse box, no bad fuses and when checking power going into under hood box all seem to have power. There is a heavy gauge wire coming and leaving box all have power, but on the fire wall there is what looks like a solenoid with 3 wires and a resistor looking unit with feed. All have power except the bigger red wire going down somewhere. I need help, I'm having a hard time finding any solution. I cant afford to go to GM shop.
