My 89 Seville has the twilight sentinel goody but it never seems to operate, and I get codes for it in history.
Diagnostic testing of the switch shows that the on/off/delay switch SEEMS to be working fine, but there is no light control...
Is the sentinel system built-in to the BCM or is it a separate box that can be replaced? I've checked all the fuses, so unless there is an external relay somewhere that's not kicking in, it is likely to be the control unit itself...
Wherever THAT is!
