I noticed that my radiator fan starts every 20s for 5s and stops when I stay for example at stoplight. Event when engine is not fully warmed.
Is it normal or there is a problem with fan switch or cooling? I didnt notice before.
I checked and found that starts only FAN2 which is related to A/C (CONDENSER FAN, on right side). How this FAN is controlled? Notice- im my situation AC is off, just started the engine.
Maybe described is normal behavior based on page AC-57 of manual.
Maybe the AC is not really off. Over here, it runs when the mode switch is in defrost or defog, even if the AC button is not pressed and the AC light is not on. I run into many people who don't believe this. It's not just toyotas either.
I understand the euro version has climate control. You may not have control over when the AC runs.
Can you get a look at what the compressor is doing when the fan is cycling?
