Guess a question is better than no answer??? LOL! The module on 92-93 cars is up behind the glovebox, a black box to the outside of the opening, rather than the smaller aluminum one toward the center. You have to remove the glovebox and door to access it, and 2 bolts into the dash support secure it. You can be certain you've found it by the 8-10 inch antenna wire sticking up and back from it.
To reword the original question:
Is it possible that both "new" modules could be defective, OR, that the aforementioned room light issue could be a factor in the failure to enter the programming mode??
C'mon guys. Who else am I gonna ask???
