BMW Repair: 89 325i dash lights, odometer and hazard, scotch brite pad, brown wires

Question
all three of these things are not working. The odometer was not working when I got the car, the dash lights just recently went out and the hazards lights do not come on

Answer
Larry,
 It sounds like you have a bad ground in the system somewhere.  Check all the brown wires under the dash (grounds) and follow them to their attachment points.  If necessary, remove the wires from their ground spot, and clean it with sand paper or a scotch-brite pad.
 
 Good luck,
 Josh
