Hi Antonio,

It looks like you are seeing what's left after your PO cut out the AC delay relay. Blue/yellow (15), black (85), red (61), and green (87). This relay was used to keep the AC from starting up until a few seconds after the engine was running.

There is a tie-in between the AC switch and the heater/blower switch designed to run the blower motor at lowest speed whenever the AC is engaged, in order to prevent evaporator freeze-up. The white/red is the wire conveying AC switch provided battery to the blower motor resistor/switch harness for that function.

To troubleshoot the blower motor power, look for a thick white/black wire bringing power from the fuse #3 to the blower switch. The motor leaves the switch on a red wire. Other than that white/red low speed tie in, there's no dependence of the blower motor on AC.

Do you need diagrams?
