You are not mentioning the condition of the 2 high amp Fuses that go to the switches and motors.
I had a good looking window fuse until I pulled it and found that the tip was burned or eroded off. The strip was not melted but it was not making contact due to the tip being gone.
Note that the Relay also has a separate fuse. On my year and model it is #12 on the fuse chart.
Also check to see that one side of the fuses is also getting + voltage.
I had a situation where one of the wires that went to a whole row of fuses had become unsoldered. That whole row did not get voltage on either side of the fuse.
