Ford Odometer Dims intermittently

Odometer displays gets dim and dark on 2005 Ford Explorer Sport Trac.

The problem is not constant,it occurs occasionally then all gets normal.

IS IT A FUSE OR BULB ISSUE?

NO,not at all.I've repaired multiple sets of these, a fuse WOULD NOT cause the intermittent issues you are experiencing, and the bulb is extremely unlikely to do so.

OK,THEN WHAT CAN CAUSE THIS PROBLEM?

Its a problem with Instrument cluster board.

The "proper" repair is to have the entire instrument cluster (the unit that holds all of the gauges and odometer behind the steering wheel) replaced. The reason this particular issue happens is usually due to a faulty solder joint on the instrument cluster.

IS REPLACING THE CLUSTER BOARD ONLY OPTION OR CAN I REPAIR THE PROBLEM?

If you go to ford dealership then for quick and easy solution.They will suggest you just get instrument cluster board replaced.
But as per my experience at our auto garage.I will say,these is jut the basic start of problem.
The problem can be repaired.

If you know how to use soldering iron and solder electric points on circuit board.Then you can repair this problem easily.

See the instrument cluster board image shown below:---
The solder points which mostly go loose are shown.

Only the odometer is affected by these solder joints
The eight solder connections in the top left of this picture are the ones that are most likely at fault, if you are comfortable with a solder gun and removing the instrument cluster, these are the solder joints that need to be repaired mostly.But if you notice any other additional solder points that seems loose then don't ignore that points. Re-solder that points too.

WHY ONLY ODOMETER IS AFFECTED AND ALL OTHER WORKS GOOD ON CLUTER BOARD?

The part of the board that has the bad solder connections gets hot and causes excessive resistance in the circuit for the L.E.D display to function constantly.The root cause of this problem is "poor solder connections" during assembly.And its not uncommon.The solder points gets loose by age and needs re-soldering.
As per the present condition,the problem is not so worse that you need to replace the cluster board.You can get it repaired by re-soldering.

If you go to a Ford dealer, they will want you to replace the entire instrument cluster.They will not do these repair work for you.

These details will help.
Thanks.

How to remove instrument cluster on 1994 Honda Accord?

Replacing instrument cluster/instrument panel is not very easy.But with proper procedure and details,its possible.
The details are as follows :-----

yes, the radio has to come out, as 2 of the trim panel screws are hidden by the radio.

This same instructions are for 1990-95 Accord
See Figures 7, 8 and 9

Disconnect the negative battery cable. If so equipped, disable the Supplemental Restraint System (SRS).
Lower the steering wheel to its lowest position.
Remove the center console.
Remove the ashtray and ashtray holder.
Remove the radio/tape player.

Remove the coin box, switches and dash light controller from the instrument panel.
Remove the mounting screws securing the instrument panel. This is a large, formed piece of plastic-don't crack it.

Lay a protective piece of cloth over the steering wheel pad.
Remove the four screws holding the instrument cluster. Pull the cluster forward enough to allow access to the wiring connectors.

Fig. Fig. 9: The instrument cluster is retained by four screws

Disconnect the wiring harnesses and remove the instrument cluster.
Individual instruments may be removed from the cluster after it is removed from the car. Avoid damage to any terminals or the printed circuit board.

To install:

Install the gauge cluster; connect the wiring before it is fully in place. Install the retaining screws.
Install the instrument panel. Make sure it is correctly placed. Install the retaining screws.
If applicable, install the air vents.
Install the coin box, switches and dash light controller.
Install the radio, ashtray holder and ashtray.
Install the console.
If applicable, enable the SRS.
Connect the negative battery cable.

This details will help.
