Hi, your Escort has 2 additional relays located on the left fender apron, they are used to control the cooling fan, one for high speed, one for low speed . Fist thing to check would be make sure that the relay you replaced is operating,if not check all fuses. Then make sure your fan motor is operational by jumpering it to battery power, replace if needed. Then check the rest of the circuit and relays using the wiring diagram.
The 40 amp fuse supplies the power to the fan, if it were blown closing the relay manually would not allow the fan to run. The 15 anp fuse is used for suppling power to control the relay, if it is blown the relay wont turn on. The other 2 relays are controlled by the PCM. If you ground the blk/red wire at the power relay it should click on and send power to the low and high relays, The pcm will turn on the relays when the fan is needed.Use the diagram I sent to identify the wires at the relays for testing.
