was going to school this morning and when i hit around 35 mph the speedo needle flew up to around 75 rapid moving back and forth between 65 and 75 with a loud ass noise. While i was still going around 45 mph. Im guessin either the speedometer cable or the VSS...any ideas? Thanks in advance. Chris

 

yeah maybe the speedometer cable....as for that noise, it might be the odometer cable

 

it would help if i knew what kind of car you had???

 

1990 chevy cavalier

 

where does the noise come from????????? thetranny or the instrument cluster?

 

the cluster...sound is coming from right behind the speedometer

 

the cable is prob loose behind the cluster.....try taking your cluster off to see if it is loose

 

alright cool...thanks for the advice ill check it out tomorrow morning. Chris

 

if i am not mistaken a 90 cavalier has an electric speedo????
