* Under the hood in the fuse box: This is the most common location. The fuse box is often located near the battery. Look for a relay that's labeled "A/C," or a position in the diagram matching your vehicle's wiring schematic for the A/C system.
* Under the dash: Less common, but some Rangers might have relays mounted under the dash, often near the HVAC controls or fuse panels.
* Behind the glove box: A less likely but possible location.
To find it accurately:
1. Consult your owner's manual: This is the best resource. The manual should have a diagram of the fuse box and relay locations.
2. Use a wiring diagram: You can find wiring diagrams online (e.g., on forums dedicated to Ford Rangers) or through a repair manual specific to your year and model. These diagrams will show the location and function of each relay.
3. Visual Inspection: Carefully examine all fuse boxes and relay areas under the hood and under the dash. Look for relays that are similar in size and shape to others in the box, and that might be labeled (even partially) for AC or air conditioning. Note that the relay may not be labeled perfectly clearly.
Without knowing the precise trim level and options on your 1987 Ford Ranger, pinpointing the exact location is impossible. The above steps are the best way to locate it.
