I have a 1996 Mercury Village GS. The front blower motor stopped working. I did lots of testing and replacing resistor and the relay. After all my testing it seems power is getting to the relay, but it goes no farther. The relay is brand new and tested and it works fine. Looking at diagrams I see no wire that runs from the relay to the fuse so could this be an internal wire or circuit inside the fuse box? Or maybe there is a wire, I'm still learning vehicle electrical stuff.

I don't know what diagram you're looking at but that relay has 2 power feeds going to it.

Yes and both the wires are live. The relay works, it clicks and has continuity. But no power is going to the 2 fuses for the blower. It's my understanding 2 power wires run into the relay, relay clicks and sends power to the fuses correct? No power is getting to the fuses. Power is passing through the relay though. So if power is going through the relay but not getting to the fuses It's my assumption there is a wire or circuit that connects the output from the relay to the fuses?

Those fuses and the relay are within the same fuse box. Are you sure the relay is activating. How do you know power is passing through if it's not getting to the fuses?

I'm assuming power is passing through since the relay is good. The relay is brand new and I tested both sides of it with 12v.
Here is the diagram I used to test the relay.

You don't know if the control head is turning it on by applying trigger ground. Pull the relay in and our and see if it clicks when plugged in with the blower turned on.

I'm guessing I should start with the Front blower motor relay control wire. I found a diagram of it(HA05 Y/R). I don't even wanna begin to follow the wire, I'm sure is ran behind the dash in a harness. What's the best way to test the wire? Don't mean to be a pain in the butt, but I'm still new to vehicle electrical.

Ok here's what I did. I pulled the fuse panel out and found the Y/R wire, applied ground from the battery and the blower fired right up. So now how do I figure out if it's the wire or a bad control unit?

Well I jumped the wire across from the control unit to the relay and I still get nothing. So am I safe in assuming it's the control unit?

The control head applies ground on the yellow with red wire coming out of it on pin 5 of the C203 connector. See if it is doing that.
Also, please reduce the size of your photos so they don't hang off the side of the page.

Check for ground coming into the control head on the black wires at pin 8 of C203 and pin 2 of C209.
