Mitsubishi lancer 1999 dash problem. The speedo, tacho, odo, temp and fuel gauge doesnt work goes on and off at different times randomly,.

what on the dash board comes on and then goes off
the dash board is that part of the car that holds the speedo , tacho, temp gauge , charge light, seat belt light dash lights , radio
add to that what make , model ,year transmission type are you talking about
as posts are not linked post again and be more specific

It may be that the speedo and temp are mechanical, whereas the tach and fuel are electrical. Check fuse for inst. cluster for clean and tight fitment. Check electrical connection at back of inst. cluster.

Maybe, a wire came lose. Did you hit anything? Spill any water inside? Could be a short, considering they all went out. Did they all go out at once?

loose plug or contact on the gauge cluster causes this problem common on neons you have to pull the cluster and adjust and clean the contacts , the test for this on my neon was when it when out if you hit the dash it would shake enough to make contact and work again

Remove the speedometer head unit, and check the soldered joints on the back. It's a common problem with these and some Chrysler products. "Randomly" is when the crack closes and makes contact, like if you hit the top of the dash and it starts working again. The speedometer head cluster.

probably burnt or cracked circuit board on back of gauge cluster

Could be a bad cluster. If one is cable driven, and the other electric. You could have a bad speed sensor in the transmission which will make the speedo not work.

the speedo is activated by the VSS in the transmission
check wires and that unit

i had the same problem on my g/f's 2000 lancer GLXi, (with tacho),
i fixed the problem by putting a jump wire on the back of the instrument cluster,
the fault was in the wiring to the tacho part & i drew up my own wiring diagrams for the cluster unit,
then traced the fault,
looking @ the back of the cluster unit, the top right hand screw for the speedometer,,, follow the track on the circuit-board, there is a link wire UNDER the board (there is a dotted line on top where it goes, i think its the left 1,,, there is 2) this track then goes to the bottom left screw on the tacho,,,
i soldered a small gauge wire from the bottom of the link solder joint (MAKE SURE ITS THE CORRECT LINK, THERE IS 2 SIDE BY SIDE) to the bottom right track on the vertical plug socket (its common pos for the warning lights) this is where the "MIRAGE" & other "CE LANCER" (without tacho) gets its speedometer & gauges power from,

kind regards waz
if anyone needs a photo i will pull out the dash again lol its only 6 screws
