My wife told me that our 12 year old knocked the map light on our 91
GL and at that instant the radio went dead and the clock stopped
displaying the time.  I checked things out when I got home from work
and all of the fuses are fine, and there is power to the radio.  I
also noticed that the horn does not work (did before). I am thinking
a bad ground somewhere.... any suggestions on where to look?  Thanks.
