Where is the relay switch or the sensor module?

Cooling fan relay is in the fuse box passenger rear of the engine compartment, fan control module is behind the glove box. Bridge the green and the black wire at the cooling fan switch and see if the fan comes on if it does the fan switch is most likely bad. Check fuse 34 (15 amp) in the under hood fuse box, and fuse #4 and #8 under the dash fuse box.
