If the relay is energizing when you supply battery power to it, does it get battery power when the car gets hot (ecm controlling it) .Most relays work with 4 pins. 30 will be power to run the fan 87 is power out (normally open pin with 87a being normally closed part) 85 and 86 are the relay coil pins (that energize it) and you should have power and ground to those pins (only when car is hot enough to turn on fan). You can also check by jumping pin 30 to 87 where the relay plugs in and see if the fan comes on.

Theft System light, but no such system on car....found the fuse that was blown and can start the engine. Initial problem was rad fan not comming on, only air conditioning fan working. Pulled rad fan relay and took battery voltage to control side of relay circuit...fan does not come on....I'm thinking I need a new fan? Relay is energizing, so circuit is good to that point...out of ideas before I have to change that fan.
what control module? there are many
what does the owners manual say?
