Speedometer doesn't move

speedometer doesn't work unless I drive it for an hour, then it will work till the next day. No codes so I guess the VSS is ok . Any Ideas??

91 3.1 v6 auto trans

I had the same problem in my Caprice... it was a loose wire to the speed sensor. I just hope it's not a broken tooth on the sensor gear, some of them are plastic.

Didn't you set a code (check engine light came on?)
my firebird has no code ...

91 did they use vacuum line or cable for your cruise control?

Also your trip and regular odometer aren't working right?

It only throws a code once in a while(light)... shut the car off start it back up, goes away, reset the codes, a month later does it again. Sound familiar?

No codes ever - No cruise controll Not an option - No speedometer -no trip- no odometer- no work - no idea- the vss is working I took the gauges out and cleaned the contacts it made it worse all the other gauges work ? it's a pissser...

Is your speedo cable run or electronic wire harness? and if Cable did you check to see if the end is wound and ifs it electrical did you check fuse panel as well as use a voltmeter to check the signal to the speedo

Don't forget the connection at the trans....

I had this problem on my 79 ta, but the source was that the line from trany was lying on the exaust pipe and got burned.
I am not sure if this is a problem on your bird, but its worth checking.

Either A Bad Connection Or Your Gear In The Tranny Has Either Popped And Slid Back On The Shaft Or Is Stripped, Takes 10 Minutes To Pull The Vss To Check The Gears.

Yeah...
Change the O-ring when you check it, or it'll leak after you put it back in.
