1996 Mercury Villager GS Blower not working

I have a 1996 Mercury Villager GS 3.0. The blower motor stopped working. I've done alot of testing from the blower back to the battery. Here's what I've tried to so far and here is what I found.
There is no power getting to the blower motor or the blower resistor. Under the hood in a fuse box is a 65a fusible link which is getting power. I replaced the relay just incase so that is working. In the under dash fuse box are 2 20a fuses from what I found with the ignition on and the heater turned on both fuses should read about 12v on the left side. The top fuse #28 reads 12v however the bottom fuse #30 does not. I'm assuming this is cause whatever controls the relay is not kicking in. Like I said I replaced the relay and I even tested the new one with a 12v souce and it clicks and works fine. If I jump the 28 and 30 together the motor starts right up, but the fuse blows and obviously that's not safe. So my question is what controls the relay in this system cause I'm assuming that's the problem. Any help would be greatly appreciated.

If you have 12v on both sides of fuse #28 with the key and blower on, then everything is working and the problem can only be the wire between that fuse and the blower motor. That fuse is on the output side of the blower relay.

Fuse 31 is only for Auto temp control systems and goes to the speed control module. That blower diagram is wrong on that. It doesn't show the speed controller or identify that leg of the circuit.
Here is the fuse diagram

That could only mean that you tested it wrong in the first place. Try swapping the relay with another one and swap the fuse too while you're at it.

There is no power getting through that fuse so you have to find out why.

Sorry to be a pain in the butt.
Looking at the diagram you posted the relay provides power to both the 28 and 31 fuse, so if the relay is working correctly shouldn't both fuses be receiving power? Also when the relay is open both sides should be open right? Or is it possible for just one side of the relay to open? If that is what's happening what exactly causes the relay to open? Does it come from the control panel where the fan speed switch is or somewhere in there?

I already told you that 31 is only used on ATC systems and then 28 wouldn't be used in that case. Yours only uses 28.
Ignore 31 on this diagram.
