Did your's have the air adjustable shocks?

Yes but they are non functional
so they leaked ? I am not sure if mine are working. No scan tool here to test that function. One of these days I should look up the performance test procedure for that system

I have never looked into it honestly. I’ve never heard a compressor, and it has always had the air suspension malfunction indicator on the dash.
The air leveling function was only in the back. "Autoride" can be the electrical shock damping control OR the air leveling system OR both. I didn't think the electric shocks appeared on the 2500's, though.
I fought with it on my '05 1500 for years before giving up (partly due to having a 2500 for towing and partly from it becoming a rustbucket/spare vehicle). The major problem is that the air compressor is mounted under the vehicle, only covered by a stupid rubber mat (to protect from stone chips?). It should be in rear behind where the jack storage stuff is and they should give you an inflator port back there, like they used to have on some Olds and Buicks. The salt will go through that pot metal crank case in a winter or two. Even without salt it's still a goner. The Arnott compressors are expensive, so I got one from some Buick which is the same basic unit. It was like $35 on eBay and by swapping all the external parts over it would run the Autoride. After that, the airbags rotted out, so I found some Bilstein replacements that are non-electric and used the fake-out loads. Soon after, the compressor was rotted through again, so I got another since I was planning to tow a trailer behind it. That compressor died, too. Not having air in the shocks lets the top of the airbag flop around and make a clunking sound, so I started pushing them down, which left the top of the shock shaft exposed. This is likely what killed the shocks, from water pooling in there to rust the shaft and take out the seal (failure mode was oil leaking up the shaft). Now it has standard AC Delco twin tubes back there.
I considered deleting the compressor and running the hoses to an inflator port and gauge inside that I could fill when needed. It was kind of neat to have the truck raise up after filling it with luggage and passengers, but I've never missed it except when pulling a trailer (the 1500's on coils are very soft). Then I could use any cigarette lighter compressor when on the road. I also considered at some point forgetting about air shocks and running the bags that go inside the coil springs. That would require fooling/scaling the pressure sensor since those standard bags run like 30psi and autoride can be over 100psi. Again, this could easily be accomplished via a manual setup.
I'm told that you can turn off the "Service Ride Control" by disconnecting the battery, pulling the fuse for the air system and reconnecting, but I haven't tried it yet.

Well I sold this Monday morning. The guy drove 4 hours and towed his 6.0 back home with it. I’m planning to go get a 1990 V20 suburban with a locked up motor on Saturday. The plan will be to drop a 7.4 tbi in it.
Not sure If I could part with my 01 8.1 burb, but then I have a K20 burb too, I think I can see where you are going.
