I walked out to my 05 CTT today to find the rear suspension slammed and the front at normal height. This is right after normal temp days going into the first cold night in a while. The Red air suspension light does come on after a few minutes of driving. The front suspension appears to be acting normally. I can raise and lower the front (until it throw the Red light) but the rear does nothing. If I hold the 'raise suspension' up it to turn regulation on/off it will only display 'Regularion Off' . This indicates to me that there is an issue either with the rear air lines or level sensors and not the compressor or accumulator since the front is working normally. I'm taking it to a buddy with a Durametric tomorrow to hopefully get more info. My battery is about 3 years old and I know the CTT can do weird things when the battery is going out...voltage was at 12.4 as measured by my crappy multimeter...could a dying battery be the cause? Thanks for your help.
