You don't get it..
When you jumper the leads on the drier, you are jumping the LOW SPEED fan circuit..NOTHING to do with the coolant temp circuit. All you have done is verify the LOW FAN circuit.
..and what does evap/drier mean??? the evap in in the cabin/dash and the dries is at the condenser in front of the car..
I assume you mean reciever/drier.
Now, lets talk HIGH FAN,,OK?
You have a relay clicking when disconnecting the blu sensor..that means the coil side of the circuit is fine , but the contactor side of the relay has NO POWER ..you have a BAD HIGH SPEED FAN fuse or wires going to the RESISTOR.
THe Battery 12v jumper to R15 has verified FAN MOTORS and the clicking relay with sensor has verified HIGH FAN relay activation..so, there is NO POWER going thru the relays LOAD side b/c you have none. FEED FUSE is where to look. If that is OK , then you could have bad contacts in relay.
So,
