The dealer found a wire that is not factory which was connected to the ride height controll module. The wire heads towards the front of the vehicle. For some reason this unexplained wire fried the module. What are some ideas as to what this mystery wire is for? My thoughts are maybe the previous owner had a manual control up front to lower the rear air suspension and maybe had shorter sport springs up front? (no air suspension for fronts). Perhaps he deleated the control when his lease was up and replaced the front springs back to stock? Does anyone aftermarket offer such system?
