AC defogger problem on 92 Lude
 

Have any of you good people had your AC cut off for no obvious reason and
then come on later without warning? I can have the AC running and notice
that the green light under the AC button has gone out. I can hit the button
repeatedly but the AC won't come back on until it gets good and ready. I
have also noticed that during these times, the defogger for the rear windows
isn't coming on either. Does this sound familiar to anyone? Is there a
control module that runs both of these units?

Thanks,
Wesley
