I need an owners manual for the 1988 ram 3500 engine

SOURCE: guages on instrument panel died 1998 jeep cherokee

Others have had this problem too. Most times it's a loose connection behind the gauge cluster.:

When you take the dash apart to get at the back of the guage you'll see that the connectors for the panel are attached to a molded piece of black plastic and the panel sits on top of them. The solution I used was to actually cut the plastic back (you can break it back too...) and insert the plugs tightly, then put a dab of hot glue on top and bottom to keep them from backing out. It keeps them nice and snug and you can remove them in one minute with a razor knife if you need to. After about a year I haven't had the problem since.

BTW - your mileage is not accurate if you have this problem. I noticed that when the gauges are off, it does not count mileage...went about 5000k miles without an oil change once...Just some addt'l info.

I know it's not a factory fix, but it costs about $1 for a glue stick and it only takes about 30min.

Hope it helps you.

need layout of fuse panel for 1994 dodge caravan

SOURCE: Chevy cavalier temp guage stopped working on instrument panel

if the wiring is good and there are no blown fuses, likely the gauge itself will have to be replaced

SOURCE: instrument panel lights defined

Check all exterior bulbs.

Could be on when headlamps are on or doors opened.

SOURCE: where is the instrument panel fuse block located?

under the glove box, you'll set a panel with 2 plastic pressure pins. using a pair of pliers, just pull from the center and remove both of them. the entire panel will be free, and the fuse block is on the far right side, (closest to the passenger door) you'll need a good light and small hands....the engineers did NOT give you a lot of room in there!
