If your guages are not working try looking for a blown fuse under the hood of your car.

They are working ,but not 100% right

the Service Indicator Board (SI Board) batteries, which are located on a small board attached to the main instrument cluster are simple Nickel Cadmium (NiCad) AA type rechargeable batteries. You can pick them up at Radio Shack for under $6. There are 2 of them, they are 1.2 volts each, and they are soldered in rather tightly. I HIGHLY recommend that if you replace them, you move the batteries to some place MUCH easier to access to change them later. Run some wire to some place else under the dash that you can more easily reach the batteries. I just tried this same thing a couple weeks ago, and ended up having to simply leave the board out entirely because the traces and solder joints had corroded so badly. My whole instrument cluster looks that way, so I am going to have to replace the whole thing eventually. ARGH!

Hope this helps Ernan, and by the way, your English isn't too bad man!

When you open cluster ,just look for board,its under "check" and all lights (fluid,oil,parking brake)

If you are looking for the ones that are "AA" type, get part number 23-191 from Radio Shack. I'm pretty sure they have to be charged before you install them. After that, the car will charge them.

ldsbeaker do you know what Radio Shack part # 87-91 i or is should use
Radio Shack don't have 3.0v barreties ,only 3.6v
