Question about 2004 Buick LeSabre

Open Question

In my 2004 Buick LeSAbre 6cyl. 3.8l, the automatic air leveling system hasn't been working (I have not heard the compressor in 4 months) and I got new tires and my shocks are all the way up and makes the ride very hard. How can I troubleshoot the air leveling and shock problem?

SOURCE: Rear shocks and compressor are

yes, you can just order them without level ride, you could also install the same ones the only thing is the air part will not be used, but if the shock without air is cheaper then just use them, i think it may be hard to get without air as seeing they all have the air ride, again if a problem just use the stock shock without useing the air,you could install hoses to shock and put your own air in them, there would be a valve you install under the bumper or where ever you like, you would ask for a air shock hose kit, easy to install. hope this helps, heres a picture of kitafc0076.jpg

I'd have them checked first to determine if it is actually the shocks, or possibly just a loose or cracked line, which should be a pretty inexpensive fix. If it turns out to be shocks, weigh it out then.

Own a 1998 Buick Lesabre Limited. The air compressor for the rear suspension only kicks on for 3-5 seconds on the initial cycle. Struts won't air up. Compressor is new,also the link on the sensor arm.


check for air leaks around the complete system taking xtra care when checking shock air connections, my mistake if you had an air leak I believe it would keep running as the sensor arm wont move to shut it off??? Also the compressor with first use of the day it should run a lot longer than 3-4 sec.

Where exactly is the switch for the air suspension compressor on a 2006 Buick Lucerne CXL?


The automatic level control (ALC) system maintains a desired rear suspension position under all types of towing, hauling, and loading conditions.
The system uses the electronic suspension control module (ESCM), ALC relay, ALC compressor assembly, air dryer, air lines, LR and RR shock absorbers with integral air chambers, LR and RR suspension position sensors, exhaust valve, driver information center (DIC), and the serial data circuit to perform the system functions.

HOW DOES BUICK LEVELING COMPRESSOR WORK?


It uses sensors to determine level of car and activates the compressor to level it to the preset settings in the control modules memory. The common problem is that the air suspension bags leak after about 75,000 miles of use. As for wiring diagrams we have none due to copyrighted material. You can find all that you need in the factory manuals, you can buy access here.

Check the level switch at the back of the car - this turns the compressor on and off as the ride height changes. It may have come loose, is stuck or faulty.

Air conditoning gets warm at idle. 1998 buick


It seems the automatic idling lifter (sensor) once you switch on the a AC system has failed and thus at low idling the Ac compressor clutch gives in stopping the compressor to spin.
You have to check tht system out.
Hope this helps!
