Before You Begin:
* Safety First: Disconnect the negative battery terminal to prevent electrical shocks.
* Gather Tools: You'll need screwdrivers (Phillips and possibly flathead), possibly sockets and ratchets, pliers, and potentially a trim removal tool to avoid scratching the dashboard.
* Replacement Part: Obtain the correct blower motor for your 1990 Suzuki Sidekick. Ensure you get the right part number.
General Steps (Subject to Variation):
1. Access the Blower Motor: This is usually done by removing parts of the dashboard. This often involves:
* Removing the glove compartment: This usually involves removing screws and possibly some clips holding it in place.
* Removing the radio and/or other components: This might be necessary to gain access to the blower motor housing.
* Removing parts of the dashboard: This can be the most time-consuming part. Carefully pry away trim pieces with a trim tool, taking note of how things are connected to reassemble later. You might need to remove screws and possibly some fasteners hidden behind trim. Take pictures as you go! This will be invaluable during reassembly.
2. Locate the Blower Motor Housing: Once you have enough access, you should see the blower motor housing. It's typically located behind the glove compartment area or lower dash.
3. Disconnect Electrical Connections: Carefully disconnect the electrical connector from the blower motor. Take a picture or note the connection points to ensure you reconnect it correctly.
4. Remove the Blower Motor: This usually involves removing screws or bolts that hold the blower motor in place. There might be a cage or housing around the motor that needs to be removed first.
5. Install the New Blower Motor: Carefully install the new blower motor, ensuring it's correctly seated and aligned. Reconnect the electrical connector.
6. Reassemble Everything: Carefully put everything back together in the reverse order of disassembly. Make sure all screws, clips, and fasteners are securely in place.
7. Test the Blower Motor: Reconnect the battery and test the blower motor by turning on the vehicle's heater/AC system. Check all blower speeds to ensure proper functionality.
Important Considerations:
* Repair Manual: A repair manual is highly recommended. It will provide specific details and diagrams for your exact vehicle model.
* Patience and Care: This is a delicate process. Take your time and avoid using excessive force to prevent damage to plastic components.
* Pictures: Take many pictures throughout the disassembly process to help you remember how everything goes back together.
* Professional Help: If you're uncomfortable with this type of repair, consider taking it to a qualified mechanic.
This is a general guide. The specifics will vary based on your exact 1990 Suzuki Sidekick model. Referencing a repair manual is crucial for successful completion of this repair.
