Dorab, Greg, q-list,

Dorab has expertly described TSB 909402, released in August of '94,
"Display Errors in Auto-Check Display"

Model(s) 100 from 1991

Symptoms:
 - with radio on, Auto-Check display shows horizontal bars or lines instead
of radio frequency
 - Unrecognizable Auto-check display - part of display is missing
 - Brake pad indicator light illuminates intermittently. (Brake pads,
sensors, and wiring are in good condition)
 - Oil warning light illuminates

Service Solution:
 - If any of the above conditions exists replace the Auto-Check circuit
board

Important:
 - If the oil warning light comes on, verify the following first before
replacing the Auto-Check circuit board:
  - Oil level
  - oil pressure
  - oil condition
  - oil leaks

Oh, Lord! I also have an exploded view of the dash showing where the
Auto-Check circuit board is.... let's just say it's not in the glove box.
If it's really necessary, I may be able to fax someone the picture of the
dash showing where the board is, and maybe I can also track down some
instructions on how to get to it, though I can't guarantee anything.
