I'm thinking my ECU for the air suspension could be bad , the Hi-Lo buttons don't do anything at all there's no flashing off light no codes are thrown the compressor will not turn on but I did put 12 volts to it and it does work so I know the compressor is good that's why I'm thinking to ECU could be bad , my height sensors are adjusted properly I took them off and took them apart they looked good inside and appear to be okay II bought some coils and put them on for now but my wife really likes the air ride so I may go back to it, I'm looking for some info on what the problem could be or if anyone has a used ECU they might want to sell, I like the ride that the coils give but if I sell it in the future it will have more value any info would be helpful thanks . Also I know that both fuses and the compressor relay are good, when I turn the key on I can hear the solenoid coming on on the compressor something is not triggering the relay to turn on the compressor that's why I was thinking bad ECU , I know this has been talked about many times any help would be appreciated thanks
