* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery. Check the diagram on the inside of the fuse box lid to identify the relay. It might be labeled as "blower motor" or something similar.
* Inside the passenger compartment fuse box: Some models have a secondary fuse box inside the vehicle, often under the dashboard. Again, consult the diagram on the lid.
* Behind the glovebox: Less common, but possible.
To find it definitively:
1. Consult your owner's manual: This is the best source of information specific to your vehicle's configuration. It should have a diagram of the fuse box(es) and clearly indicate the location of relays.
2. Use a wiring diagram: A wiring diagram specific to your 1993 Ford Explorer will show the location and path of the blower motor relay circuit. You can find these online through automotive repair websites or forums, often by searching "[Year] [Make] [Model] wiring diagram."
3. Visual inspection: If you can't find it in the fuse boxes, carefully examine wiring harnesses and relays under the dashboard and under the hood. However, be cautious not to damage anything.
Without knowing the specific trim level and options on your 1993 Ford Explorer, pinpointing the exact location is impossible. Using the steps above, you should be able to locate it. Remember to disconnect the negative battery terminal before working with electrical components.
