Suspension is sitting extremely low. Electric air ride suspension, though I cannot figure out if the compressor is out or the struts themself. I'm assuming the compressor, as all 4 struts went bad at the same time, though how can I go about checking this?
-Usually all four wheels are tucked under the fenders as the car sits so low, though sometimes only three(the front left is the one that varies).
-When they were slowly going out, I would hear a hissing from the suspension after the car was turned off.
-Changing the ride height has no effect.

The first thing to check would be the compressor, check all fuses and see if compressor is running.
i can tell you that most air bag systems develop a leak in the bags and the problem is not fixed inturn the air compressor runs so much to fill leaking bags that it over heats and destroys the compressor. most of the time the compressor fuse will blow, so check fuses first and then compressor. I have never seen a 1992 lexus with air bags.
It's always possible that letting the car sit for long periods of time can adversely affect the air ride suspension but it's not always the case. A leaking air bag is quite common on that model. If after you start the car the bags fill up, then you've confirmed that the compressor is working and the most likely problem is a bad air bag. Depending on where you live, there are companies that specialize in air spring repair instead of going to a dealer where you pay top price for both parts and labor. There are also replacement kits available for doing the job yourself as well as alternatives to the air ride suspension with standard parts. I hope you found this post to be helpful. Best of luck!
I bought an '02 Bravada a couple months ago. I was told that this is normal. Since it's an air ride suspension the air escapes when the vehicle is not in use like overnight. Then after starting up the air compressor will turn on and inflate the air ride suspension.
You probably have a leak in the system. Did "they" check the lines and air suspension? "They" probably disconnected the compressor to keep it from burning out from overuse. You need to fix the leak before reconnecting or the compressor will wear out very quickly.
If this light is flashing, there is a problem somewhere in your air suspension system. You can check to make sure its powered on in the trunk on the driver side. Behind the carpeting. This is a common issue with that particular year and model. The system tends to go bad righ around the 15 year old mark or so. Also if the light is flashing, the system is not working. Your just riding on the regular suspension.
