Speedometer not working, mileage clock goes to

1st hook up a scan tool and verify the vehicle speed sensor is outputting a signal on the scan tool, if that is ok then the dash cluster is likely the problem and will need to be rebuilt..

Bad ground wire somewhere in the dash .

check the ends of the cable [male &female ] they might be rounded off

Find the speedo cable at transmission and see if it is loose.

I would say its probably a short or a ground problem at the turn switch or a wire in that area. you need a test light and probably a multi meater and some nohow a ground or wireing problem can even drive a master teck crasy.

Symptoms point to the cluster microprocessor. How was it proven? See diagram below.

Pretty common problem with these. Here's a guide to learn how to fix GM instrument clusters yourself, I used it to fix mine and it worked great.How to guide for Silverado instrument cluster repair

does it now rest at zero with car stopped? if it doesn't then probably the little spring called the clock spring is broken. on most cars it's pretty involved to fix this, you will have to take the dash apart to get to it. hope that helps

I replaced the radio with an aftermarket one and now my dash lights, power windows and my headllights have dont come on automataclly like they did before. my alarm on my remote dont work either, I think i did something to the alarm system, that is why they are not working.

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
