Technical Service Bulletin # 95-T-27B
Date: 980401
Clicking, Ticking or Rubbing Noise from Odometer
BULLETIN NO.: 95-T-27B
ISSUE DATE: April, 1998
GROUP/SEQ. NO.: Electrical-13
CORPORATION NO.: 5883O3R
SUBJECT:
Clicking, Ticking or Rubbing Noise from Instrument Cluster Odometer (Replace Speedometer/Odometer Assembly)
Due to the addition of 1997 vehicles and 1998 vehicles originally produced with a mechanical odometer, and the availability of a revised remanufactured
service part, this bulletin supercedes bulletin 95-T-27A, which should be discarded.
MODELS AFFECTED:
1995-1997 Saturns and 1998 Saturns originally produced with a mechanical Odometer. (Refer to parts requirements for VIN breakpoints)
CONDITION:
Some customers may comment that an excessive clicking, ticking or rubbing type noise can be heard from the instrument cluster assembly while driving
the vehicle.
IMPORTANT:
A very slight clicking noise is normal due to the odometer design which increments in steps rather than a continuous motion.
CAUSE:
Displacement of dampening grease internal to the odometer stepper motor.
CORRECTION:
Verify that the clicking/ticking or rubbing noise can only be heard while the vehicle is being driven and that the frequency of the noise is proportional to
the vehicle speed.
If the condition is verified, replace the speedometer/odometer assembly according to the procedure in this bulletin.
Procedure
IMPORTANT:
For the procedures in this bulletin, refer to "Instrument Panel and Console" section of the "1995 Body/Repair Service Manual," or the 1996, 1997 or
1998 "Audio System & I/P Cluster Service Manual," depending on year of vehicle being serviced.
1.
Remove instrument cluster assembly.
NOTICE:
Failure to use the anti-static mat (SA 9502Z) properly may result in damage or latent damage to the cluster electronics.
2.
Remove speedometer/odometer assembly from instrument cluster assembly.
IMPORTANT:
In order to prevent the possibility of a rattle condition between the speedometer or tachometer frame and the instrument cluster housing. Insulator
material should be applied to instrument cluster housing prior to installation, if the insulator material is not already present.
3.
Inspect instrument cluster housing for insulator material.
^
If insulator material is not present, proceed to the next step.
^
If insulator material is present, proceed to step 7.
4.
Partially raise left side of the tachometer assembly by releasing both locking tabs, but do not remove the tachometer assembly from the instrument
cluster housing.
