Hey guys have read a hundred post it feels like on this. I have been troubleshooting the cdl on the 96 I just got running. When I shift into 4l I get no lights or relay clicking sound. I have taken the sensor of t case and cleaned. When I jump the sensor I get the cdl and abs light. My question is what is the next step to get the cal to engage I have been driving around in the driveway gravel in all gears forward and reverse and the relay never click or gives me the whirling noise from the motor??
