I have an 88 SSE and it sags a bit in the rearend, I can hear a buzzing sound but it doesn't inflate. Does anyone know what I can check to even make sure the compressor is even working??????? Any help will be greatly appreciated. Thanks, George

I believe if you hear the buzzing that the compressor is working fine, but you might have a leak in your air shocks.

See if you can get any air pressure from the inflator in the trunk.
