Digital speedo 1991 gmc jimmy no longer worky

[Colt9699 10+ year member]

Any ideas from the Jimmy/Blazer crowd?

All my other gauges work fine, just the speedo and turn signal indicators no longer work?

I have been told to just replace the dash but they arekinda expensive.

Any input would be appreciated. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

what fuse should i be checking?

 

[get_r_done_fire 10+ year member]

take a look at the fuse box cover and there should be something about dash light and turnsignals or parking light.

It's not a fuse, the power supply on the gauges pooped out.

Same thing happened to the digital gauges i put in my '90 s-10

Pick up a new motherboard off of ebay, they go for $70-100 shipped. It will fix your problems (it did for me)

ummm, yes it will.

Check some of the other auctions.

I had the same exact problem as you, I replaced the motherboard, and all the gauges worked.

Some of the auctions even show pictures of what it'll fix, some of them showing the odometer and speedometer not working.

Try under the hood. Many cars have a second fuse box und the hood. I know I lost the electronic dash on my 91 Cougar and that's where my problem lay.

Before you spend money, check the obvious things //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Ummm, it says RIGHT IN HIS AUCTION that it WILL fix the problem.

I don't know what that guy is smoking.

"If your digital speedometer exhibits any or all of the following, I have a replacement for you.......

* Any of the gauges display intermittently

* Speedometer and or odometer display not working

* Gauges not working

* Missing digits or segments in any of the gauges

* Odometer displaying "error" or missing digits

* Burning smell

*

All dead except the indicator bulbs (service engine soon,brake, etc) "
