What would cause the speedometer to work intermittently in a 1994 Volvo 940T? Everything else on the instrument panel works fine (including the cruise control although I don't know what speed I am going)
If the speedometer and odometer are not working the problem is usually lack of signal from the transmission speed sensor.
But if the cruise control works and the speedometer does not, my guess would be a problem inside the cluster.
SOURCE: speedometer don,t work
Depending on whether your speedo is mechanical (uses a cable), or electronic (uses an electrical wire to carry the signal from the sender), I would look it (what's in between the speedo and trans speed sender) before replacing the instrument panel. A good service manual that includes a dash wiring diagram should help trouble shoot this problem.
Good luck.

hi, sounds like the vehicle speed sensor mounted on the transmission is going bad or loosing signal. generally, honda speedometers work for life, i've only ever replaced one. now, this is a split year so it may have just a cable going to the transmission instead of an electronic sensor. if the cable is loose, this may also cause this issue. you should probably have a professional shop take a look as the speedometer cable/sensor is very buried in the back of the engine compartment under the air intake hose and behind the starter. also, if there is a check engine light on when the speedo stops working, this should be an easy diagnostic for a technician to do, it would likely be the speed sensor causing this engine light.
SOURCE: Cruise control will just turn off by itself
The speedometer may need to be replaced, it tells communicates
with the cruise control to monitor the speed...

neoprene gear in transmission were the speedometer cable goes into transmission should not have a dished appearance if you pulll it out of transmission look at it from the side it should appear flat from the start of the gear to end of gear no dish down in center

Can
be loose speedo wiring connectors under instrument panel or its issue with
speed sensor on transmission.
