The fluorescent backlight is going bad. It might bounce back intermittently. Hope it doesn't do this during state inspection, if you have that.

    To tell you the truth, I don't know anyone who has owned this car and fixed this problem.

    We never had a problem with ours. Other things broke down on it though.

    The fact is, that it has to do with the printed circuit board component(s) that are burnt out.

    I don't know myself how to fix the problem, and I don't know any technicians who are good enough

    or knowledgeable enough about this problem on Ford Digital Displays from the 1980s.

    It turns out that Ford guarded the proprietary design and building of the electronics found in these

    cars so they could charge a premium back in the 80s.

    So, the final answer is that it's not fixable by a technician here in Pennsylvania, anyway.

    If you knew the person who designed and built the digital dash, that would be another thing.

    But, they probably have since retired from their job at Ford Motor Company. It's been 25 years since

    1985 when the Ford Thunderbird was built.

I want to put a 700r4 in a 86 suburban 7.4liter for better gas milage.lts a 8 lug so do i have to change the rear end also?

No, your rear gears should match well with the 700R4, which is quite possibly the best automatic transmission ever produced by GM.

13 mpg highway. 2003 2500 4x4 5.7 litre 94000 miles on it. is there some things i can do to help milage?

Unfortunatly there is not much room for improvement on these trucks. A tonnou cover helps, proper tire inflation helps as well. You can get a hi flow air filter like the K&N these help some. You can get a little better milage with the higher Octane gasolines but you have to pay more for the gas which is kind of a wash on this. 12-13MPH is about what I get regularly on my 06 2500 6.0ltr, 14-15 if the wind is pushing and I keep out of the gas. What gears are you using in the rear end. A gear change to 3.73 will improve milage but less power and the gear change is an expensive repair.

Digital dash displays not working or displaying correctly

Sorry but unless you have very good working knowledge of small intergrated circuits then you will not fix it....There are comon issues with them. You can remove it and have a dealer send it out for you for repair but you cant drive the vehicle. If you do the milage will change in the pcm but will not match the odometer so the pcm will lock the vehicle when you put it back in. Your best bet is to have the dealer send it out or buy a new one with the milage programed into it.

2002 Volks. Jetta - digital display for odometer, clock, gears

Mine went blank after condensation inside windshield dripped behind the dash (sunroof drain problem). After a few months, in really dry winter weather, digital display time, gears, odometer came back. I assume water inside dash just needed time to evaporate. Sure beats $1000 to replace unit inside dash!

Odometer does not work

This is a common problem with all models of volvo, with the non digital odometer  pre 1998,, there is a tiny nylon gear deep inside the odometer that needs to be replaced. Your dealer will not fix it, but will put in a new one for you as the cost of fixing in labour is more than a new one,, My solution is much cheeper,, I have
many low milage VOLVO odometer/instr clusters, a few hi'r km 1s

I have many pre 1998 Volvo instrument clusters, most with Very low milage, almost all in Km, I have most models of Volvo.

at these prices IT'S A GOOD IDEA TO HAVE AN EXTRA ONE , comes with detailed instructions -with pictures-on how to remove your old one and re-install

just for example
I have 4,, 1994-1997 850/s70/v70 /c70turbo with less than 10,000 km
2 1994-1997 850/s70/v70/c70 non turbo with less than 10,000 km
1 1990 740 -940 turbo with less than 4.000 kms

I also have many Volvo instrument clusters from 1987 to PRESENT with varied milage,,let me know what year and model and milage you are looking for,, I will have something close

2003 Chevy 2500HD Dash Gauges not working

In my case, simply removing and reseating the IPC/DIC fuse restored the gauges to full functionality.
