2004 buick rainier. I have never owned a vehicle with air suspension. When the car is parked for long periods the back end lowers. Upon starting i can hear the compressor is that normal?
It is not normal for the car to leak down,there must be small leak in air ride system,but if it take a while to leak down,it should not be a big issue,as long as the compressor pump,s it up when you need it to.
