Where is the constant control relay module on a 96 ford windstar 3.8?

There isn't a single component specifically called a "constant control relay module" in a 1996 Ford Windstar's electrical system. The functionality you're likely looking for is distributed across several relays and control modules. To find the source of a specific control problem, you'll need to be more specific about what's not working.

For example, are you having problems with:

* A specific electrical component? (e.g., headlights, power windows, blower motor) This will help pinpoint the relay or fuse related to that component.

* Engine starting or running? This points towards the Powertrain Control Module (PCM) or related relays.

* Something else entirely? Provide more details about the symptom.

Relay locations in a 1996 Windstar are typically found in the underhood fuse box (often located near the battery) and sometimes in the interior fuse panel (usually under the dashboard). The Powertrain Control Module (PCM) is usually located near the firewall, often under a cover.

To find the correct relay or module, you need a wiring diagram specific to your 1996 Ford Windstar 3.8L. You can find these diagrams in a repair manual (like a Chilton's or Haynes) or online through automotive parts websites (some offer free diagrams with registration). The diagram will show you the location of each component and its associated wiring.
