Just bought a 97 grand am se. The abs and traction control light are on. I went to auto zonE and got a code reader. It didn't show any issues. Any one know how I can figure out how to diagnose the problem? Also when I was in the trunk the light was disconnected. When I re connected it to the first connection all the doors unlocked. I disconnected it and tried the other connection and it worked. Any one know what this connector might go to? Thanks in advance
