With that in mind, let’s cut right into the chase.
The 2005 Buick Lesabre’s air compressor is under the vehicle itself. You’ll find it in an enclosed section right under the chassis.
But to do this conveniently. You’ll first have to raise the car using vehicle lifts or hydraulic jacks, chocks, and jacks. But I usually recommend the vehicle lifts since it guarantees safety better than other choices.
See this video by Uncle Mark to see how a typical air compressor is located on a Buick Lesabre. Watch until the 5th minute.
The failure of the air suspension compressor can be difficult to identify since the air suspension compressor is a part of the air suspension system as a whole. So, anytime you discover any of these signs, you should perform a full test on the suspension system as a whole.
Here they are:
- Your Lesabre Buick sinks on all four sides: There is a normal level which a car rides, and even when there are loads in the trunk, the air struts would balance out the weight of the load.
But what happens whenever there is a likely air compressor fault is that the air compressor fails to collect air needed to keep the struts functional and thus, the car just sinks.
- Bumpier and uncomfortable journeys: The air ride system exists to improve comfort for the passengers of a vehicle. Once you notice that each ride becomes uncomfortable as the mileage count increases, then it could mean the suspension system is faulty somewhere and it could probably be the air spring compressor.
- You hear a hissing sound coming from below the chassis of your Buick. It could mean many things but one of those things is that the hose linking the air compressor to the air reservoir is damaged or it could even signify even more serious damage.
- Offroading becomes stressful and less enjoyable; The air suspension system guarantees that the person on the driving wheel is protected from the impact of the car against rugged terrains but when the air suspension system gets bad. The driver feels the impact, and what’s supposed to be fun ends up being misery (in some cases).
How To Know If The Air Suspension Compressor Is Bad
Now that you have noticed any of the aforementioned signals, the next thing to do is actually confirm whether your air suspension compressor is actually damaged or not. Do this by carrying out the following;
- Swapping out the air suspension compressor with a new one. If the air suspension works after doing this, then you know it’s the compressor that’s faulty.
- Even cheaper, carry out a hotwire test on the air suspension compressor relay. So many times, it could be that the relay which is supposed to power on and off the air compressor is the faulty one and not the compressor as a whole.
If the hotwire test seems technical for you, swap the air compressor relay with a new one. But make sure the new one has the exact pin like the one you’re swapping out.

Question; Is there a permanent alternative for an air suspension compressor?
Answer; No, there is not! The closest alternative is the plastic tire inflator but it is deemed for use in cases of emergencies and as such cannot be considered a permanent replacement for air compressors.
Question; Are air suspension compressors made of plastic?
Answer; No! This is because plastic would easily melt under the high heat condition the air compressor normally operates. Hence, aluminum is a preferred material for making the air suspension compressor.
Question; Does the air compressor send air to the air suspension directly?
Answer; No, pressurized air flowing from the air compressor is first stored in an air reservoir where it is promptly made available to the air suspension when need be.
