  Q: How to replace gauges in the instrument cluster, and what are the legal requirements for odometer readings during replacement on Volvo 940?

  A:

  The gauges can be replaced individually on some models, while others necessitate the replacement of the entire gauge cluster assembly, which contains various components such as modules, printed circuit boards, fuses, and sometimes small microprocessor computers for the clock and driver information center. Diagnosing this system is complex and costly, as most parts are special order only, making trial and error replacement impractical; therefore, it is advisable to diagnose the failed component before replacement. For models allowing gauge replacement, the instrument cluster should be removed, followed by the cluster cover, and then the retaining devices, which may include bolts or tabs, to take out the gauge from the cluster, with installation being the reverse of this process. In cases where the entire cluster must be replaced, the instrument cluster is removed, the printed circuit board and any necessary components are taken out, the cluster cover is removed, and the instrument cluster retainers are unfastened to extract the gauge cluster assembly. When replacing a speedometer or odometer assembly, or the instrument cluster, federal law mandates that the odometer reading of the replacement unit must match the prior odometer's mileage; if this is not possible, the replacement must be set to zero, and a proper label must be affixed to the driver's door frame indicating the previous odometer reading and the date of replacement.

  Q: How to remove and install the Instrument Cluster on Volvo 940?

  A:

  To remove and install the cluster for 240, 700 Series, 940 Models, and Coupe; first disconnect the negative battery cable, then remove the molded plastic casings from the steering column. Next, remove the bracket retaining screw and place the bracket down toward the steering column and remove the cluster attaching screws, disconnecting the speedometer cable. Tilt the cluster out of its snap fitting and disconnect the plug and if equipped with a tachometer disconnect the tachometer sending wire before lifting the cluster out of the dashboard. For installation purposes, place the cluster in the dashboard, making sure the wire and speedometer cable are reconnected before snapping it down and ensuring it snaps its connections. Install the cluster attaching screws, replace the bracket and the holding screw, install the moulded plastic casings on the steering column and reconnect the negative battery cable. For models not using 240, 700 Series and 940 Models and Coupe, start by disconnecting the negative battery cable and opening the glove compartment. Disconnect the swing-down arms from the glove compartment door, remove the screws to the lining, and disconnect the passenger side air bag module. Remove the screws over the glove compartment and under the air bag module, as well as over the instrument cluster and remove the panel vents and side demister vents. Remove the retaining screws behind the vents, the dash speaker grilles and speakers, followed by the dash panel retaining screws under each speaker grille. Remove the instrument panel cover using the attached passenger side air bag module, remove the holding clips on the instrument cluster, lift it from the dashboard and remove connectors attached at the back of the instrument cluster to remove the instrument cluster. For installation, replace any light bulbs in the instrument cluster by twisting the light bulb counterclockwise to remove and clockwise to put the new light bulb. Connectors on the back of the cluster assembly are connected, inserted and retaining clips are connected. Then place the instrument panel cover and install the retaining screws, then the vents, dash speakers and grilles. Install air bag module retaining screws, plug in air bag module connector, install glove compartment lining and lid and finally reconnect negative battery cable.
