To get to it, you'll likely need to:
1. Remove the glove box: This provides access to the area behind the dashboard. The glove box usually has a few screws or clips holding it in place.
2. Locate the blower motor housing: Once the glove box is out, you should see a metal housing. The blower motor is inside this housing. It may be attached with screws or rivets.
3. Disconnect the electrical connector: Before removing the blower motor, disconnect the electrical connector supplying power to it. This is a crucial safety step to prevent accidental shocks.
4. Remove the blower motor: This may involve removing some screws or possibly even removing the entire blower motor housing depending on the model.
Important Considerations:
* Consult a repair manual: A repair manual specific to your 1987 Jeep Wrangler YJ Sport is highly recommended. It will have detailed diagrams and instructions, making the process much easier and safer. A Haynes or Chilton manual would be a good investment.
* Take pictures: Before disassembling anything, take pictures so you can remember how everything goes back together.
* Be careful with wiring: Be gentle with the wiring harness and connectors to avoid damaging them.
* Use the right tools: You'll likely need screwdrivers (Phillips and flathead), possibly a socket set, and potentially some pliers.
Without a repair manual specific to your vehicle, providing exact instructions is impossible. The access method might vary slightly based on trim level or any modifications made to your Jeep. Again, a repair manual is your best resource.
