General Steps:
1. Access the Blower Motor: This usually involves removing parts of the dashboard or accessing it from under the dash. The exact location and method depend on your Bronco. You'll likely need to remove some trim pieces, possibly the glove box, and potentially even the steering column shroud. Your repair manual will be crucial here.
2. Disconnect Electrical Connections: Locate the electrical connector(s) supplying power to the blower motor. Carefully unplug them. Take photos if you need to remember their positions for reassembly.
3. Remove the Blower Motor Housing: The blower motor is typically housed within a cage or housing. This housing might be held in place with screws, clips, or a combination of both. Carefully remove these fasteners and take note of their location and order.
4. Disconnect the Blower Motor: Once the housing is removed, you'll see the blower motor itself. It's likely held in place by screws or other fasteners. Carefully remove these fasteners to free the blower motor.
5. Remove the Blower Motor from the Housing: Often, the blower motor is simply held in the housing by the mounting screws. Once those are removed, you can pull the blower motor out. There may be a little resistance due to the shape and size of the housing.
6. Inspect the Housing and Ducts: While you have the blower motor out, it's a good opportunity to inspect the blower motor housing and associated ducts for any debris, obstructions, or damage. Clean as needed.
Important Considerations:
* Repair Manual: A repair manual specific to your 1979 Ford Bronco is invaluable. It will have detailed diagrams and instructions specific to your model and year.
* Safety First: Always disconnect the negative battery terminal before working on any electrical components.
* Tools: You'll likely need a variety of screwdrivers (Phillips and flathead), possibly sockets and ratchets, and potentially some pliers or other tools depending on what you encounter.
* Patience: This can be a somewhat fiddly job, requiring patience and careful attention to detail. Take your time to avoid damaging any parts.
* Photography: Take photos as you disassemble the components. This will be extremely helpful when reinstalling everything.
If you're uncomfortable working on your vehicle yourself, it's best to take it to a qualified mechanic. Removing the blower motor can be tricky, and improper reassembly could lead to further problems.
