The 1985 Electra standard speedometer contains a quartz mechanism. Buick is pleased to announce an exchange repair program for quartz speedometers

parts.
Quartz speedometers are serviced by the exchange units listed below.
(AN EXCHANGE UNIT IS AN ASSEMBLY CONSISTING OF A DIAL, POINTER, MECHANISM, AND CIRCUIT BOARD, TWO ODOMETERS,
A MOTOR, SHIFT INDICATOR, AND FUEL GAUGE, ASSEMBLED TO A "DUMMY" HOUSING. THE HOUSING HAS NO FLEXIBLE
CIRCUIT, CLIPS, LAMPS, ETC.; ITS SOLE FUNCTION IS TO PROTECT THE REST OF THE EXCHANGE UNIT DURING SHIPMENT. TWO

An exchange quartz speedometer may be obtained by telephoning one of eight service centers. (For your convenience, all have toll-free numbers.) The
requested exchange unit will be shipped via UPS within 24 hours, along with a billing. The memo billing will be canceled when the inoperative unit is
received by the service center from which you obtained the exchange unit.
Please adhere to the following procedure when a vehicle requires dealer service for an inoperative quartz speedometer
1.
Follow the diagnostics procedure in the Service Manual precisely and completely. Many doubts perceived by the observer to be in the
speedometer may be with remote the sensors and connectors. Proper diagnostics will identify the source of the condition and avoid unnecessary
removal and shipping of functional assemblies to service centers.
2.
When diagnostics are complete and it is determined to be in the speedometer, call one of the service centers, and request the appropriate exchange
unit. Tell the service center the mileage to which the odometer should be set.
3.
After the exchange unit is received from the service center, remove the inoperative speedometer from the instrument cluster.
4.
Remove the exchange unit from the reusable shipping container. Remove the "dummy" housing from the exchange speedometer, and assemble the
speedometer to the instrument cluster. Use care in handling the exchange unit. Hands must be free of dirt and grease. Avoid touching electronic
components on the circuit board, as electro-static discharge can cause some components to fail.
5.
Assemble the inoperative speedometer to the "dummy" housing and pack it in the reusable shipping container, together with all five copies of the
