FLICKERING SPEED CNTRL. SW. BACKLIGHT / INTER. HORN OPERATION WHILE TURNING
APPLICABLE MODELS/VINS
1995 B-Series
DESCRIPTION
A flickering speed control switch backlight or intermittent horn operation may occur while turning in cold weather. When the vehicle is cold, the electrical ground in the steering column (which passes through the steering shaft bearings) can become intermittent while turning. This is caused by the bearing grease freezing and forming a thin barrier that reduces electrical continuity.
An updated wiring harness which adds a ground through the steering column to the steering wheel switches is available to correct this concern.
Customers complaining of this concern should have the vehicle inspected and if necessary, have the harness installed.
REPAIR PROCEDURE
1. Record all preset audio Stations.
2. Disconnect and isolate the battery terminals.
3. Remove the driver's side air bag according to the procedure in section S of the BETM.
CAUTION:
After disconnecting the battery terminals, wait one minute before servicing or removing any air bag system components. This precaution will prevent accidental deployment.
4. Remove the speed control switches, if equipped. Refer to section Q of the BETM.
5. To remove the steering wheel. Refer to Fig. 1.
^ Remove the retaining nut.
^ Remove steering wheel using a two (2) jawed puller.
