Here's a general procedure:
1. Remove the glove box: This typically involves removing screws or unclipping it from its hinges. Consult your owner's manual or an online repair guide specific to your van's model for detailed instructions. Some models require removing other parts like the knee bolster or lower dash panel to reach it.
2. Locate the resistor: Once the glove box is out, you should see a small, usually black, rectangular box with several wires connected to it. This is likely the blower motor resistor. It might be mounted directly to the HVAC housing or secured with clips or screws.
3. Visual Inspection: Look for any obvious signs of damage like burning, melting, or loose connections.
Important Considerations:
* Year and Model: The exact location can vary slightly between years and models. Searching for a repair video on YouTube specific to your *exact* 1988 Ford van model (including the E-Series designation, like E150, E250, etc.) will be highly beneficial.
* Owner's Manual: Your owner's manual might contain a diagram of the dashboard components, including the blower motor resistor location.
* Online Repair Manuals: Websites like Chilton or Haynes offer repair manuals for older Ford vehicles. These often have detailed instructions and diagrams.
If you can't find it after removing the glove box and looking carefully, you may need to consult a repair manual or seek assistance from a mechanic. Trying to blindly search without proper guidance could lead to accidental damage to other components.
