This post is regarding a 96 Sport with a standard AM/FM/Casette stereo
system.

The light for "Speed Control" and the button lights on my radio no
longer light up when I turn the dash lights on.  The radio display
doesn't dim when I turn the lights on, either.  It's almost like the
radio and that Speed Control light aren't getting the signal that the
lights are on.  I checked fuses, paying particular attention to:

3  Parking lamps
7  Illum. switches
10 EATC system, Rear blower, Speed control, GEM system, Brake interlock,
Overhead console, Automatic Ride Control
20 Radio, Power antenna, GEM system, Anti-theft, Cellular phone
29 Audio system

No fuses appear to be blown.  I removed the ones listed above to make
sure.  I examined the rest of them in place, and they looked OK.

I pulled the radio out and checked the electrical connections, and they
appear to be properly connected.

The switches on either side of the radio are lit up properly.  I haven't
seen anything else that isn't working right.

Does anyone else have any ideas?
