Hey Stormmin===It depends on what kind of car and what year. If it is an electric speedo, it can be the speed sensor or in the head. If it is a manual it is in the head. GoodluckJoe
pickup speedometer does not register from a cold start. Shifting lurches and then all evens out after about 30 mph
its a 1994 cavalier the speedometer runs on its own and will not start it starts when the speedometer is not running it has the vs sensor
No, but you could start one or register on his website. No, but you could start one or register on his website.
register
Actually , it doesn't have a conventional speedometer cable , it has an electronic speedometer and a vehicle speed sensor ( VSS ) according to my Haynes repair manual
Start with the vehicle speed sensor the feeds the speedometer and odometer.Also look at the Brake/Speedometer problem associated with the Windstar recall for a leaking brake pressure switch
I would have the driveline u joints checked as well as the front end parts to start.
Try asking your question again - it makes no sense as presently written. If the vehicle won't start - then it won't run. If it won't run how can the speedometer needle be bouncing? (?????)
Take it 2 a repair shop idiot
you have to take the dash apart...that is the speedometer assembly. once you start to take the cluster off, the speedometer cable is snapped onto the speedometer. you take that apart and the cable will pull out. be sure to put your bolts that you pull out of the dash in order so you do not confuse where they go...plastic strips easily.
Register problems will start building up. Eventually the register will have problems which can cost you.
as soon as you start the vehicle it should register
