When the fan is connected directly to the battery it runs very smoothly but it won't when it is connected to where it's supposed. There are no faulty fuses but I just replaced the 30A fuses with new ones and even bought a new fan, but it still doesn't run. But the car can start smoothly.

Hi,

There are two different wiring schematics listed for this vehicle's cooling fan circuit. Both incorporate a fan relay. Have you checked the relay itself? If not, see if there is another relay in the box having the same part number and switch them. If there isn't, here is a link that explains how to test the circuit:

I attached both schematics below so that you would have a reference. When you check the relay, make sure there is power to it.

Let me know.

Joe
