Before you begin:
* Disconnect the negative battery terminal. This is crucial to prevent electrical shorts and injury.
* Gather your tools: You'll likely need a screwdriver (likely Phillips head), possibly some pliers, and a replacement blower motor resistor. It's helpful to have a flashlight for visibility.
Location of the Resistor: The 1996 Ford Ranger resistor is *usually* located behind the glove box or under the dash near the blower motor. Some models have it integrated into the blower motor housing, making access more difficult.
General Steps (Assuming under-dash access):
1. Remove the glove box: This usually involves removing screws from the sides or hinges of the glove box. Consult your owner's manual for precise instructions if necessary.
2. Locate the resistor: Once the glove box is out, you should see the blower motor and potentially the resistor. It's typically a small, black, rectangular unit with several wires attached. It might be secured with screws or clips.
3. Disconnect the electrical connectors: Carefully unplug the electrical connectors from the resistor. Take note of how they're connected for reassembly. Take pictures if it helps.
4. Remove the old resistor: Unscrew or unclip the old resistor from its mounting location.
5. Install the new resistor: Mount the new resistor in the same location as the old one, ensuring it's securely fastened.
6. Reconnect the electrical connectors: Carefully plug the electrical connectors back into the new resistor, matching the connections to how they were before.
7. Reinstall the glove box: Put the glove box back in place and secure it with the screws.
8. Reconnect the negative battery terminal.
9. Test the blower motor: Turn on your vehicle's ignition and test the blower motor on all speeds. If it works correctly, you've successfully replaced the resistor.
If the resistor is inside the blower motor housing:
This is more involved and usually requires removing the blower motor itself. This often involves removing the air intake ductwork from under the dash and possibly more disassembly. This process is considerably more difficult and might require specialized tools. Searching YouTube for "1996 Ford Ranger blower motor resistor replacement" will yield videos that may demonstrate this approach, but be aware that it can vary depending on the specific model of Ranger.
Important Considerations:
* Owner's Manual: Always refer to your owner's manual for specific instructions and diagrams relevant to your vehicle.
* YouTube Videos: Searching for a video specific to a 1996 Ford Ranger blower motor resistor replacement will provide visual guidance. Remember that the location and access can vary slightly.
* Professional Help: If you're uncomfortable working on your vehicle's electrical system, it's best to seek professional help from a qualified mechanic.
Remember safety first. If you are unsure about any step, consult a mechanic. Working with car electrical systems can be dangerous if not handled properly.
