My SUV had a body lift and a new bumper installed. Now the tachometer, speedometer and the temperature gauges fail to work. Additionally the check gauge, check brakes and the battery icon are all lit up. And the digital read out is not functioning properly.

The car starts and the MAF is still working.

The car has been in three shops and it is driving me crazy.

I look forward to your help.

Hello my name is Dave.

First thing that comes to mind is a ground issue, I would make sure the ground strap that goes from the engine to the body is intact and both ends are tight. This a common issue that creates a great deal of issues especially with Ford products (I'm a Ford man myself). If you can check that and make sure the ground from the battery to the engine block and body are all in good shape. If they are in good shape we can move on to more complicated diagnosis procedures.

I have attached a diagram showing where the grounds from the battery are located.

If you can check those and let us know your results we will be glad to guide you further if need be. Please keep us up to date on your progress and thank you for using 2CarPros!

Electrical problem
2002 Ford Explorer 6 cyl Two Wheel Drive Automatic

Hello everyone,

I have a problem with my 2002 Ford Explorer Sport Trac, my instrument cluster backlights do not luminate when I turn on my headlights. I checked the fuse that is supposed to correspond with the circuit and it appears to be fine. Can anyone tell me what the problem could posssibly be.

Thank you

Check behind the dash to make sure none of the wiring harnesses are loose or damaged. Also, the power for the dash lights comes from the headlight switch. You may want to have that checked.

Gauges not working and message center, but the car still runs. I have checked all the fuses.

Hi,

Did this happen all at once? Does the speedometer anything work? I attached a pic below of two fuses I want you to check. In addition to just checking the fuse, confirm there is power to it and out from it.

If there is power, you will next need to confirm the power is getting to the cluster. On the pic, you can see the wire colors and pin locations. Also, make sure the connector is tight and not damaged.

Here is a link you may find helpful when checking the fuses and for power to them:

Let me know what you find.

The light is on because one of the gauges are low or not working. Which gauges are not working?

If the wiring is good going to the cluster, tight, and not damaged, first make sure there is power going to the plug in. If there is, the cluster itself is most likely bad.

Let me know what you find.

I have a ford explorer and the instrument panel stopped working. No Tach, speedo, fuel, temp or volt meter. Is there a specific fuse for it or any suggestions? Thanks

Do you have electronic dash? Check the ribbon connector, and or, any others, behind the dash, might be some work to get to it, I have heard of issues with it on other vehicles.

I took my 2003 ford explorer the ford dealer to have the oil changed and when I picked it up it was fine. However, that same day when I turned the car off and then turned it back on for later use none of the instrument gauges worked. Windows would not roll down, the 4x4 would not work, the paddle lights would not work, etc. I took it back to the dealer the next day and they said it wasn't anything they did b/c they only changed the oil. They connected my car up to the computer for diagnosis, then checked and replaced fuses trying to assess the problem. Two hours later they said they believed the problem to be the instrument cluster. Okay I have them order the part and replace it as according to them the instrument clusters just go.

I pick up my car after they have had it for over a week and I am told that I need to bring in the keys for reprograming of the car. I take the keys in and wait for the reprograming. Once they say its done I go and get into the car and notice that the paddle lights on the vehicle still don't work and the interior lights are not working either. I go back in and tell the serviceman what is going on and he tells me that that part may have missed reprogramming and that I need to bring it back in tomorrow for that.

I do so and when I call to get my car I am told that they could not fix the problem b/c there is another problem, their diagnosis found that the central junctin box has an internal short and needs replacing, the cluster cost me over $300 dollars and now they say that this part is going to cost me $280 dollars. Do these parts just go out? Do they go out in conjuction with the other as they have stated? Should the computer diagn. The first time have been able to determine that both parts needed to be replaced the first time?

Do all these problems happen at once. If so I would suspect a main fuse or a relay problem, if ok, the G.E.M. Which controls the fuctions metioned, could be bad. When you got it back did the gauges work?

All of these problems happened after I picked up my car from having the oil changed. When I got the car back from having the instrument cluster changed it was then they told me that the junction box needed to be changed since the paddle lights on the car would not work or the internal lighting when you open the doors.

That doesn't look good. I would take it to a different dealer for a second opinion.
