Where is radiator fan switch for 1996 ford Windstar?

The radiator fan switch (also referred to as the cooling fan switch or engine coolant temperature sensor, depending on the system design) for a 1996 Ford Windstar is typically located on the engine block or near the thermostat housing. In most cases, it's mounted either:

On the intake manifold, close to the thermostat, or

Near the cylinder head, depending on the engine type (3.0L or 3.8L V6).

In the 1996 Windstar, the engine control module (ECM) often uses input from the coolant temperature sensor (CTS) to control the radiator fan, rather than a standalone "fan switch." This means if your fan isn't coming on, the issue could be related to:

A faulty coolant temperature sensor,

A blown fan fuse or relay,

A bad fan motor, or

A wiring issue.

If you're troubleshooting a cooling issue, it's a good idea to start by checking the fuse and relay box under the hood, then test the fan and temperature sensor.
