Hello All,

Problem started immediately after pulling the dash and instrument cluster off to access transmission shifter cable and replace brake-shift interlock.

Instrument cluster repeats the following sequence consistently about every 8 seconds either while vehicle is running or key is in ON position.

Vehicle continues to operate normally while driving.

Vehicle: 2010 Ford E350 Superduty cut-away bus, 170k

Sequence detail:

1. Oil Pressure/ tachometer / fuel / temp / charge / odometer / trip meter /cluster backlight - go dark, analogue gages go to zero

2. analogue gages return to normal but cluster backlight is remains off

3. All warning lights in center of cluster – light up brightly

4. Odometer - lights up brightly (headlights Off mode)

5. Warning lights in center of cluster - go off

6. Odometer/brake/airbag/ battery/ engine -remain on

7. Odometer/brake/airbag/ battery/ engine -off & on very briefly, then Trip meter lights up

8. Cluster backlight returns to normal, odometer brightness returns to normal (headlights On mode)

Time for above sequence about 4 seconds. Time to repeat about 10 seconds.

Attempted fixes:

Checked Cluster fuses, OK.

Checked cluster plug for looseness. Reassembled. Same problem.
