Volvo v40 1998 manual

SOURCE: 1991 Volvo 740GL Speedometer

I remove two panel underneath the steering column. The first panel is removed using a 10 mm socket. The second panel is removed using a torx socket (can't remember the size). Removing these two panels gives you room to get to the clip on speedomter. Looking at the speedometer, you should see two rectangular holes on each side of the speedometer cover. I use a awl to push in the clip (you could use a screwdriver). Looking underneath the dash, you should be able to see the clip you are pushing on with the awl. I take my 2nd awl and put it behind the clip. I get the left side to release. One the speedometer cover releases, you can see the speedometer. You will see the 4 torx screws (t20) and two smaller clips holding the speedometer. All that is left is the wiring. (I take a sharpie pen and mark one of my wire locations on the speedometer. I am not sure what it does. It is a single wire.)

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.
