Just noticed the radiator fan on my 156 twin spark 2.0L is not working. Possibly a fuse? Where should I look to replace if necessary. Any other likely causes?

Not sure which fuse it is, but check the connections around the radiator

I started this thread: Link when my TS fan failed.

Sometimes the connectors break up, so worth a look

Likely cause usually is fan speed resistor. Short the connctor for it if you suspect it and if it then works you have your answer.

It will come on at normal temp this way but speed is uncontroled so tis temp fix only

From memory (and I am probably wrong) there is a relay near the battery for it? Try re-seating it.

With the ignition on unplug the temp sensor and see if the fan comes on.

If not,

Turn off the ignition and directly power the fan from the battery, does it run now?

If yes then it's either the Resistor (normally), relay (occasionally), wiring (rarely).
