2008 Nissan Armada LE Rear Air Suspension Compressor Not Working: A Troubleshooting Guide

The 2008 Nissan Armada LE is a full-size SUV known for its luxurious features and impressive performance. However, like any complex vehicle, it can be prone to issues with its air suspension system. In this article, we will focus on troubleshooting the rear air suspension compressor not working in a 2008 Nissan Armada LE.

The air suspension compressor is a critical component of the air suspension system, responsible for compressing air to maintain the vehicle's ride height. If the compressor is not working, it can cause a range of symptoms, including:

Uneven ride height: The vehicle may sit lower on one side than the other, affecting its stability and handling.
Bouncing or sagging: The vehicle may bounce or sag excessively, especially when driving over bumps or uneven terrain.
Air leaks: The air suspension system may leak air, causing the compressor to work harder and potentially leading to premature wear.

In your case, you have already replaced the ride height sensor and rear air struts, but the issue persists. This suggests that the problem may be more complex and require further troubleshooting.

You have already disconnected the power to the compressor, which is a good step in troubleshooting. However, it's essential to understand the electrical system of the air suspension compressor to proceed with further diagnosis.

The air suspension compressor is typically controlled by an electronic control unit (ECU) that receives input from various sensors, including the ride height sensor. The ECU sends a signal to the compressor to activate or deactivate it, depending on the vehicle's ride height and other factors.

Given that you have already replaced the ride height sensor and rear air struts, here are some additional troubleshooting steps you can take:

Check the compressor's electrical connections: Ensure that the compressor's electrical connections are secure and not damaged. Check for any signs of corrosion or wear.
Inspect the compressor's air lines: Inspect the air lines that connect the compressor to the air suspension system for any signs of damage, kinking, or blockages.
Check the compressor's oil level: The compressor's oil level should be checked regularly to ensure it is at the recommended level. Low oil levels can cause the compressor to overheat and fail.
Use a multimeter to test the compressor's electrical circuit: Use a multimeter to test the compressor's electrical circuit to ensure it is functioning correctly.

If the above troubleshooting steps do not resolve the issue, it may be necessary to replace the compressor. When replacing the compressor, ensure that you purchase a genuine or OEM replacement part to ensure compatibility and quality.

When working with the air suspension system, it's essential to follow proper safety procedures to avoid injury or damage to the vehicle. Here are some additional tips and precautions to keep in mind:

Always refer to the owner's manual: The owner's manual provides valuable information on the air suspension system, including troubleshooting and repair procedures.
Use proper tools and equipment: Use proper tools and equipment to avoid damaging the vehicle's components or causing injury.
Work in a well-ventilated area: The air suspension system contains compressed air, which can be hazardous if not handled properly. Work in a well-ventilated area to avoid inhaling compressed air.

Troubleshooting the rear air suspension compressor not working in a 2008 Nissan Armada LE requires a systematic approach. By following the steps outlined in this article, you can identify and potentially resolve the issue. Remember to always refer to the owner's manual and follow proper safety procedures when working with the air suspension system.
