Tools You'll Likely Need:
* Socket wrench set (metric)
* Screwdrivers (Phillips and flathead)
* Pliers
* Ratchet and extensions
* Possibly a torque wrench (for proper tightening)
* Wire cutters/strippers (if splicing wires)
* Electrical tape or connectors
* Shop rags or towels
General Steps (Consult your repair manual for specifics):
1. Disconnect the Battery: This is the most important step. Disconnect the negative (-) terminal first to prevent short circuits.
2. Access the Wiper Motor: This is often under the hood, behind the cowl (the area where the windshield meets the hood). You might need to remove various components to gain access, such as:
* Cowling: This plastic cover often needs to be removed. Look for clips and screws holding it in place.
* Wiper Arms: These will need to be removed. There's usually a nut or bolt under a cap at the base of each arm. Make sure to mark their position before removing them to ensure proper reinstallation.
* Other Components: Depending on your specific model, you may need to remove other parts like the air intake duct or other under-hood components to gain better access.
3. Disconnect the Electrical Connector: Unplug the electrical connector from the wiper motor. Take a picture or note the wire arrangement before disconnecting, in case you need to refer to it later.
4. Disconnect the Linkage: The wiper motor is connected to the wiper arms via a linkage. Carefully disconnect this linkage. Again, take note of how it’s connected.
5. Remove the Wiper Motor Mounting Bolts: The motor will be held in place by bolts. Remove these bolts carefully. You may encounter some resistance due to corrosion.
6. Remove the Wiper Motor: Once the bolts are removed, carefully remove the wiper motor.
7. Install the New Wiper Motor: This is the reverse of the removal process. Ensure the linkage is properly reconnected and the electrical connector is securely plugged in.
8. Reconnect Everything: Reinstall all removed components in the reverse order of removal, making sure everything is securely fastened.
9. Reconnect the Battery: Reconnect the battery positive (+) terminal.
10. Test the Wiper Motor: Turn on your wipers to test the functionality of the new motor.
Important Considerations:
* Corrosion: Expect to encounter corrosion, especially in older vehicles. Use penetrating oil (like PB Blaster) to help loosen rusted bolts.
* Repair Manual: A repair manual specific to your 1994 Dodge Ram is invaluable. It provides diagrams and detailed instructions that are crucial for a successful repair. Don't try this without one.
* Safety: Work in a well-lit area. Be mindful of sharp edges and moving parts.
This is a general overview. The specific procedures will vary depending on the year, model, and trim level of your 1994 Dodge Ram. Always refer to your vehicle's repair manual for the correct procedure. If you're uncomfortable performing this repair yourself, it's best to take your truck to a qualified mechanic.
