Tools You'll Likely Need:
* Socket set (various sizes)
* Ratchet and extensions
* Screwdrivers (Phillips and possibly flathead)
* Pliers (needle-nose might be helpful)
* Wire connectors (if you disconnect the wiring harness)
* New wiper motor (ensure you get the correct one for your Aztek)
* Shop towels or rags
* Possibly a trim removal tool to avoid scratching plastic
General Steps (This is NOT a complete guide; use a repair manual):
1. Disconnect the Battery: This is crucial to prevent electrical shorts and injury. Disconnect the negative (-) terminal first.
2. Access the Wiper Motor: This is where a repair manual is essential. The Aztek's wiper motor is likely located under the dashboard, possibly requiring partial dashboard removal. You might need to remove some trim pieces, possibly the steering column shroud or parts of the lower dash panel. Expect some fiddly work here.
3. Disconnect the Wiper Motor Linkage: The wiper motor arm will be connected to the wiper transmission linkage. Carefully disconnect this linkage. Take photos or make notes before disconnecting to ensure correct reassembly.
4. Disconnect the Electrical Connector: Unplug the electrical connector from the wiper motor. Again, take pictures or notes if the connector is complex.
5. Remove the Wiper Motor Mounting Bolts: The motor will be secured with bolts. Use the appropriate sockets and carefully remove them.
6. Remove the Wiper Motor: Once the bolts are removed, carefully extract the wiper motor. There might be some resistance due to its location.
7. Install the New Wiper Motor: Reverse the removal process. Carefully align the new motor and install the mounting bolts, tightening them to the manufacturer's specifications (found in your repair manual).
8. Reconnect the Electrical Connector: Carefully plug in the electrical connector.
9. Reconnect the Wiper Motor Linkage: Reattach the linkage to the new motor, ensuring it's properly aligned.
10. Reassemble the Dash: Carefully reassemble all the dash panels and trim pieces you removed.
11. Reconnect the Battery: Connect the battery positive (+) terminal first, then the negative (-) terminal.
12. Test the Wiper Motor: Turn on your wipers and check that they operate correctly in all speeds.
Important Considerations:
* Repair Manual: A repair manual is absolutely essential. Generic instructions like this are insufficient for a complex repair like this.
* Patience: This is a time-consuming job requiring patience and careful attention to detail.
* Safety: Always disconnect the battery before working on electrical components. Be cautious when working around sharp metal edges.
* Professional Help: If you are not comfortable performing this repair, take your Aztek to a qualified mechanic.
