1. Locate the Blower Motor Resistor:
* The blower motor resistor on a 1995 Buick Riviera is typically located behind the glove box (passenger-side compartment). However, some sources suggest it might be located under the dash on the passenger side. You'll need to locate it visually; it's a small rectangular or square electronic module.
2. Access the Resistor:
* Glove Box Removal (Most Likely): This is usually necessary. You'll likely need to remove the glove box entirely to gain sufficient access. Consult your owner's manual or a repair manual specific to your vehicle for the exact steps, but generally involves:
* Removing screws holding the glove box in place (usually located on the sides and possibly at the top).
* Unclipping any retaining clips.
* Carefully lowering the glove box.
* Dash Access (Less Likely): If the resistor is under the dash, you'll need to carefully remove or at least partially loosen some of the dash trim panels to gain access. Again, a repair manual is crucial here to avoid breaking anything.
3. Disconnect the Electrical Connectors:
* Once you locate the blower motor resistor, carefully disconnect the electrical connectors attached to it. Take note of which connector goes where, and take pictures if it helps.
4. Remove the Old Resistor:
* The resistor may be held in place by screws, clips, or simply friction. Carefully remove the old resistor from its location. Again, refer to any diagrams or instructions in your repair manual.
5. Install the New Resistor:
* Install the new blower motor resistor in the same position as the old one. Make sure it's seated correctly.
6. Reconnect the Electrical Connectors:
* Carefully reconnect the electrical connectors to the new resistor, matching them to their original positions.
7. Reinstall the Glove Box (or Dash Panels):
* Reassemble the glove box (or dash panels) in reverse order of removal. Make sure everything is securely fastened.
8. Reconnect the Battery:
* Reconnect the negative battery terminal.
9. Test the Blower Motor:
* Turn on the ignition and test the blower motor on all speeds. If it works correctly on all speeds, you've successfully replaced the blower motor resistor.
Important Considerations:
* Repair Manual: A repair manual specific to your 1995 Buick Riviera is highly recommended. It will provide detailed diagrams and instructions to avoid damaging your vehicle.
* Electrical Safety: Remember, always disconnect the negative battery terminal before working with any electrical components.
* Parts: Ensure you purchase the correct replacement blower motor resistor for your 1995 Buick Riviera. The part number should be verified through a reputable parts supplier using your VIN.
If you're not comfortable working on your car's electrical system, it's best to take it to a qualified mechanic. Improper installation can lead to further damage or even electrical hazards.
