1986 300 SDL 110K miles.
Today I noticed a slight hum coming from the area above the steering wheel.
The oil pressure, temp, and speedometer guages all are suddenly not working.
Also, the glow light indicator and sound don't come on when starting the car.
Otherwise, car drives fine. I had a new radio put in a couple of days ago but
this is probably not related, although I asuume it is an electrical problem. Can
anyone tell me what is wrong? Thanks,
Fuses are all ok. However, the buzzing noise is coming from a black box
1" x 3" in the fuse box which says 12V/2(4)x21W. I looked it up on mbz.org
and it says multi-function relay for blinger, hazard, wiper and rear window
Doesn't say anything about gauges.
Here again are the symptoms: all the gauges (oil, speed, temp) not working.
Relay in fuse box is buzzing (blinker relay).
Blinkers work and buzzing stops when signaling left or right turn.
New radio installed last week (@ Circuit City), but symptoms appeared
only several days after.
My guess is that the multi function relay is ok, but there is a short circuit
somewhere causing it to buzz as well as causing the gauges not to
work. I'll see my mechanic later this week but has anyone experienced
similar problems? Thanks,

Get a test light, connect the clip end to a good ground, turn on the ignition,
check each fuse for
12v at each end at the brass terminal. Both ends will light the test light if it
is a hot circuit
and the fuse is good. You will find a cracked fuse.
