I need a fuse diagram, our speedometer does not work, neither does our seat belts work automatically. The drivers side seat belt is locked in the off position. We felt it may need a new fuse. We have changed the instrument cluster on the odometer.
BCM being faulty is the most common cause of this concern
The odometer has failed
If the speedometer and odometer are both not working, I would blame the speed sensor. If only the speedometer does not work and the odometer does work, the cluster is bad.
There are two possible actions: 1) Replace the speedometer head assembly, because that is where your problem is. 2) Ignore the broken odometer and forget about it. The speedometer and odometer are one assembly. The same input that drives the speedo also drives the odometer, so you have a problem in the head itself.
it usually is the gear in the transmission Could be the vehicle speed sensor.
The logical problem - would be a broken speedo cable. The speedo & odometer are both run from the same cable.
probably need to replace the speedometer cable. if turbo check the big one that goes along the firewall possibly got burnt up on the down pipe
If the odometer is not working but the speedometer is still indicating speed, the most likely fault is a set of small plastic gears inside the speedometer instrument itself. I have seen these gears available for sale at various BMW parts specialists. Removing the dash cluster for access to the speedometer is not difficult in a 1987 E30 car. With the cluster on the bench, you can repair the speedometer gears or replace the whole thing. Used speedometers are plentiful at on-line auction sites such as eBay.
due to contraction of heart
there is no separate drive for the odometer, so it's the gauge... also, everyone should have a manual for their vehicle, and the library should have a professional manual available...in the reference section, you'll have to make copies of the important sections...good luck :)
Cruise will NOT work if the speedometer has a problem
A bad/dirty vehicle speed sensor (vss) or bad wiring will cause this. the sensor is usually a magnetic pickup and any metallic dust stuck to it will affect the signal clean the sensor or get a new one
