I have an 156 JTS where the cooling fan dosen't kick in. I've change the thermostat, coolant sensor and the fan resistor and still it won't turn on. The fan is working cause i can easily turn it on with wire directly from the battery. I can't see why it wouldn't turn on automatically, i can turn the fan on manually with obd cable and software, and here i can hear the clicking from the relays so they are working as well, it just won't turn on automatically. Any ideas?
