Default Engine Cooling fan

I have a 98 Camry with 130K - V6. When thecar is stone cold should the cooling fan come on even before the engine starts? I don't think it used to do that.
Thanks,
Russ

Check the coolant temp sensor in the radiator, it may be diffective.

The fan is also wired to come on if the sensor electrical plug comes off or a wire breaks.

The AutoZone website at www.autozone.com should have a wiring diagram for this car and info on the fan cooling system.

Finally got the car to our mechanic. He found that the AC High Pressure switch was bad. That was causing the fans to think the car was hot and causing the a/c compressor to not function properly so we were getting no defrosting of the windows. He, in my opinion, is very good. The bill for that diagnosis and for the part and recharging the a/c system was $193.00. Seemed reasonable to me.
Thanks for the suggestions.

That would do it also. This switch is in series with the coolant temp switch.

Thanks for taking the time to follow-up with an explanation of the culprit and outcome.
