Troubleshooting Hints - Instrument Panel Dimming

1. If the I/P lights will not dim when using the I/P dimmer switch, check the gray (8) wire for a short to the B+. If OK, replace the headlight switch.
2. If the I/P lights dims erratically when using the dimmer switch, check the I/P dimmer switch for a poor connection. If OK, replace the I/P dimmer switch.
3. If one or more of the I/P bulbs will not illuminate, check the gray (8) wire for voltage at the location of the inoperative bulb. If voltage exists, repair open in blk/wht (151) or blk (150).
