DESCRIPTION
In some 1986 B2000 there is a possibility of the parking lights remaining on after the light switch is turned to the "OFF" position due to insufficient
clearance between the contact points in the light and turn switch.
For this reason you are requested to replace the light and turn switch at P.D.I. or as soon as possible if the vehicle is within the VIN range listed below.
LABEL LOCATION
NOTE:
If the vehicle has a blue or purple label attached to the left or right upper corner of the windshield or the underside of the column cover, the repair has
already been made at the production facility or prior to the distribution to your dealership.
