1. Access the Blower Motor:
* Locate the Blower Motor: The blower motor is typically located behind the glove box or under the dashboard on the passenger side. You'll likely need to remove or at least partially dismantle the glove box assembly.
* Remove Glove Box: This usually involves removing screws or clips holding it in place. Carefully note how it comes apart for reassembly. Some models might require removing the entire glove box, others only a portion.
2. Disconnect Electrical Connections:
* Unplug the Wiring Harness: Carefully disconnect the electrical connector leading to the blower motor. Take a picture or make a note of the connection points for easier reassembly.
3. Remove Blower Motor:
* Access the Motor: Once the glove box is removed (or partially removed) you should have visual access to the blower motor housing. There might be a few screws holding the motor housing in place. Remove these screws.
* Remove the Housing: The blower motor may be held within a housing that needs to be removed before the motor itself can be accessed.
* Remove the Blower Motor: The motor itself may be held in place by several more screws or possibly clips. Carefully remove these fasteners. Sometimes the motor will just pull out, other times you may need to carefully manipulate it to clear any obstructions.
4. Reassembly:
* Reverse the removal process to reinstall the blower motor.
* Ensure all electrical connections are secure.
* Securely reattach the blower motor housing and glove box.
Important Considerations:
* Repair Manual: A repair manual specific to your 1996 Cadillac DeVille is highly recommended. It will provide precise instructions, diagrams, and torque specifications. This is crucial to avoid damage.
* Tools: You'll likely need various screwdrivers (Phillips and possibly flathead), possibly sockets and wrenches, and possibly some trim removal tools to avoid scratching the dashboard.
* Patience: This process can be somewhat involved, particularly with accessing the blower motor. Take your time and be methodical.
* Safety: Always disconnect the negative battery terminal before working on any electrical components.
If you are not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Improperly removing or reinstalling the blower motor can cause damage to your vehicle's electrical system or HVAC system.
