Hey Robert,

If your Air Lift WirelessAIR Compressor System for Air Helper Springs # AL74000 isn't deflating the air springs on command then you either have a low or high voltage issue or the manifold on the compressor is overheating or too cold. Test the voltage with a multimeter # PT89ZR to see if the voltage is the issue and then you can trace the lines to the power to fix any issues you find. If the power isn't the issue then the manifold might need to warm up first or if too hot be relocated away to a space that generates less heat.
