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.)

Volvo gle 850 1996


After I bought my '96 850, I found it had the same problem. In my case the speedometer worked fine, but not the odometer. A little research on the internet revealed that it's a common problem with these models.

There's a motor that drives the odometer separately from the speedometer, and the weak link in the chain is a tiny gear that turns the odometer when the motor runs. That gear is easily broken and even one missing tooth will disable your odometer.

The fix is relatively straight-forward, but requires you to remove the instrument panel and disassemble it in order to get to the motor housing and the broken gear. You won't have any trouble finding replacement parts on eBay that are much better made and will last you the rest of the life of the car. The difficulty level on this is about medium, but be careful when you've got the instrument panel disassembled; I wasn't cautious enough and ended up with a couple of my indicators out of alignment; my tachometer read zero when it was idling, and my fuel gauge only went up to 17 gallons when it was full, so I had to take it all apart again to reposition the gauges to get them to read correctly.

1994 Volvo 940T Speedometer Works Intermittently


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.

Hi, I have a volvo 740 made in belgium 1991 model. The speedomete spent a few months fluctuating wildly, sometimes working well, sometimes not at all, sometimes stuck on 140 km per hour. The odometer...


There should be a speedo sensor on the transmission somewhere. I don't know exactly where it is located. I believe your speedo is all electrical so the sensor on the transmission sends a signal to the speedo head. You can go onto some parts stores websites and see if one is listed for it, if it is, I would try replacing that first. I don't think the part should be more then $50 or $60 but you never know with Volvo. Good luck.

the odometer part of the speedometer has more than likely broken, or is just work out. you can't replace just that part of it either, you'll need to look around or search google for a replacement speedometer. bear in mind that some laws come into play when replacing the speedometer / odometer on a vehicle as well.

Odometer quit working

Odometer is turned by a mechanical gear wheel, which is the likely culprit.
