Air Ride Suspension...Service Suspension Message Won't Quit

[LadyRed]

I bought a 2010 GMC Yukon XL in 2019. The air ride was shot on it (someone had hit and damaged the compressor). I took of the compressor and installed front and rear springs/struts. BUUUUTT I've tried all suggestions listed on threads here and that stinking "service suspension" light won't quit! I even took it to my buddy and had him try, just to make sure I wasn't missing something. No luck. Any other suggestions to stop the dang alert?

Probably needs resistors, you didn't clarify what "all suggestions" were, there could be tons of erroneous information out there

what chassis trouble codes is it trowing? It’s easier to fix if you know that.
