Bought a 96, triple locked with factory elockers. The front and center lock works fine but the rear locker just blinks and doesn't engage. I exercised it by doing figure 8's to no avail. Also, when I purchased it the PO tried to get it to engage and when it wouldn't he said the ABS light came on. Does have pin 7 mod. I did change the front ABS sensors which didn't help. Possible the two are related? Any ideas on a solution. The PO said he checked the actuator and said is was working and that I needed to pull the axles apart and re-align it or something. Thanks in advance. This is my first 80, so I am learning.
