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 blinker, hazard, wiper and rear window heater. 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,
