Temp light on, fans not working

97 familia, 1.5L manual.

Driving home the other day...bumped the kerb lightly as I parked up then temp light came on. Have tested relays, fuses, coolant temp sensor, thermostat ( all working as normal)....fans won't kick on at all.

(Haven't tried jumping fans straight from the battery as it's !#^&^$^ down outside and am 1 month post op so still a bit sore lol)

This is really starting to do my head in.
