SUBJECT: HEADLAMP SWITCH TRIM PLATE ASSEMBLY REPLACEMENT
MODELS: 1986-1991 S/T TRUCKS
Some 1986-1991 S/T trucks may experience a cracked plastic headlamp switch trim plate. This may result in the inaccessibility of the rheostat assembly
(dimmer switch) and/or the switch assembly (headlamp/park lamp switch) (Figure 1).
Figure 1-Plate Assembly-Instrument Panel Switch Trim
Previously, it was necessary to replace the complete headlamp switch trim plate assembly. The complete assembly includes the rheostat assembly part
number 01995293 (instrument panel dimmer switch), switch assembly part number 01995313 (headlamp/park lamp switch) and the switch trim plate
(Figure 1), and the switch trim plate hole covers. A new trim plate kit is now available which does not contain the rheostat assembly or the headlamp
switch. This kit replaces the complete headlamp switch trim plate assembly when the switch trim plate is cracked and the rheostat assembly or the
headlamp switches do not need replacing. This new kit includes; a switch trim plate, bracket for switch mounting, covers for the switch trim plate holes
and four bolts/screws.
