NOTE: A MANUFACTURING CHANGE INSIDE THE FUSE BLOCK TO ELIMINATE THIS CONDITION WAS MADE ON SEPTEMBER 20, 1990. THIS BULLETIN DOES NOT APPLY TO CARS BUILT AFTER THAT DATE.


SYMPTOM/CONDITION

REPAIR PROCEDURE

This repair consists of installing the PN 4604149 jumper wire which has an integral .22 microfarad capacitor to reduce the voltage spike coming from the power seat motors.
