I think that you gave me clue as to what your concern may be. You stated that the instrument panel lights are adaquately illuminated for a brief second before they go dim. The Ford interior lighting system is designed to dim when the headlights are on. I am guessing that you may have auto-lamps equipped on your vehicle? If so, see if they are coming on at the time the interior lights go dim. Shut the auto-lights off for a test; if that works and you are in daylight when they are suppose to be off, look for something such as a dash cover blocking the sunload sensor that is mounted to the top of your dash. I have seen just last week a person with the same issue.

Yes I have an automatic lights switch, but it makes no difference in the overall intensity of the odometer light when the lights are on, off, or on automatic. Yes when I start the car in my garage, the head lights do come on immediately. I do think that there may be a problem with the Interior lighting system but don't know where it is, or how to test so I know if it is the problem or not.

The Sunload sensor is clear, Can you tell me what modules are in the circuit for the odometer and associated computer output intensity. So far I have 1. sunload sensor, 2.dimmer switch, 3. some kind of control module, 4.LED readout in instrument panel. Is this correct?

Yes, and this is where I will give you an answer that you may not like: A repair facility with the capabilities to test and monitor BCE modules is the next step. There is a couple of these modules including the instrument cluster (which is a module itself) needs to be tested for diagnostic trouble codes and monitor the inputs and related outputs that are in the circuit. I do not know any other way.

OK, Thanks for the answer, this is what I was looking for if it means taking it to the dealer and having them do the testing, that is fine. I always like to know what is involved before I do that though.
Thank you
