Recently I've noticed that the two left digits of my digital mileometer display are not as bright and clear as the ones to the right. Is this display illuminated by a bulb or bulbs, if so I can't see why it's partly dimmed and not just failed as would happen if it was a bulb or is the whole display digital meaning that two digits are failing?
Thanks.

 

There are bulbs behind the odometer, I think you need to remove the instrument cluster to get to them.

 

Thanks for that. At least now I know. Not looking forward to the prospect of removing the cluster though. The dimming digits aren't that bad!
Thanks again.

 

It's not hard to do, 4 screws from underneath and then it comes out. Have the steering wheel as low as it will go, and as far out as it goes. Actually seeing the screws can be the hard part, they are deeply recessed. Lie in the footwell and look up and you'll see them, on the front edge of the cluster. A flashlight helps too.

 

Thanks for that, as a matter of interest are the bulbs clear or if not, do you know what colour they are?
Thanks again.

 

The bulbs are a bluish green. I believe the part number is LNA5180CA, but I'm not 100% sure. There are 2 sizes of base and I don't know if that's the right one.

 

Biffta, did you give the cluster a good couple of whacks with your knuckles? Sometimes a little coercion will "repair" a loose bulb connection. Possibly save you a removal job.

I thought the bulbs were the common clear push-in type. But i could be wrong. Foggy memory from last time I saw the cluster out of the car.

 

No I didn't. It's normally my first action with any problem. Will try it!
Thanks.

 

BTW, the screws you are referring to are they below the "ledge" which protrudes from the instrument panel and in which the switches are fitted?
Also, found this link to removal and unless I'm mistaken, the removal process seems to be different! Bit confused now.

Bifta,
The removal process shown on the link is correct. You have to remove the trim panel in the drivers footwell, then there are four screws, then as the binnacle is coming out, you need to unplug the two electrical connectors. Having had the pleasure more than once, it is definitely not a big job.
The link then goes on to explain how to open the instrument pack, which may be where the confusion arises, but that too is not a complicated task, and is fairly obvious when you have the pack in front of you.
Contrary to what was said earlier, from memory the instrument pack bulbs are clear rather than blue/ green, but again, this will be obvious when you have it apart.

 

Thanks so much. Really appreciated.

 

Yes. I was assuming the trim panels were removed, sorry for not making that clear. I did it yesterday at the junkyard on a 94 XJ40 and the trim comes off first. That's just a few screws.

And yes, once the instrument cluster is removed it has to be taken apart, but again that's just a few screws.

 

Thanks for that, appreciated.
