Figure 1-Plate Assembly-Instrument Panel Switch Trim
Some 1986-1991 S/T trucks may experience a cracked plastic head lamp switch trim plate. This may result in the inaccessibility of the rheostat assembly
(dimmer switch) and/or the switch assembly (head lamp/park lamp switch) (Figure 1).
Previously, it was necessary to replace the complete head lamp switch trim plate assembly. The complete assembly includes the rheostat assembly part
number 01995293 (instrument panel dimmer switch), switch assembly part number 01995313 (head lamp/ parking 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 head lamp switch. This kit replaces the complete head lamp
switch trim plate assembly when the switch trim plate is cracked and the rheostat assembly or the head lamp 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.
