I am getting service suspension system warnings. The air pump would not turn on. I replaced it and the only way to make it pump up is using a jumper wire with the relay under the hood disconnected. I checked the relay and its fine, plus I bought a new relay and it still wont work. So does anyone know what makes the compressor turn on. no matter how much weight I put on it , it will not turn on.
