I have a 97 850 that has an intermittent problem with the speedometer, odometer and cruise control. When they work they all work perfectly, but with no rime or reason they all stop working together, maybe for 10 minutes, maybe for 10 days.


Any one else experience anything like this

 

Sounds like fuse/relay/wiring is loose/bad connection/faulty.
Check your fuses, and replace the one for that circuit even if it looks ok. I've had ****ty fuses trick me before.

Then I'd say you might need to get behind the dash to check the connection isn't loose there. I don't know anything about circuits, but i get by. It works or it doesn't
