The dash lights should now be on at full brightness. Using a fused jumper wire with a 10 amp fuse, connect the orange wire at terminal “B” to the dark green wire at terminal “K”. If power is not present on the green wire after the above conditions are met, disconnect the harness from the headlight switch. If power is present when the above conditions are met, the switch is not the problem. This wire supplies power to the ILLUM fuse in the driver’s interior fuse box. The panel dimming switch also needs to be rotated to the full bright position. Terminal “K”, dark green wire should have power with the park and/or headlights switched on. Power is supplied via the PARK LP fuse in the underhood fuse box. Terminal “B”, orange wire should have power at all times. Sorry, no pictures of actually removing the screws and installing the new switch but, I did get some pictures of the switch to let you have an idea of how it is mounted.įurther testing of the wiring to the switch should be done before replacing the switch. The switches can be unplugged and the panel removed to access the interior screws for the headlight switch assembly. With all of those steps completed the dash trim panel can now be pulled or unsnapped from the dash. I tilted the column all the way down and placed the shifter handle down to D1. I also had to drop the lower dash trim panel to access two more 7 mm headed screws ath the bottom edges of the main dash panel. I had to remove one 7 mm headed screw from the trim panel above the instrument cluster. The list of illuminated devices include the instrument cluster, radio, a/c controls, steering wheel controls and dash mounted switches. If there are any illumination bulbs on the problem is not the switch the problem is blown bulbs. Then check all of the bulbs for operation. If there is power on the ILLUM fuse place the truck in a dark location or use a blanket to cover the dash. If they are also not working check the 20 amp PARK LP fuse in the underhood fuse box.

This is actually pretty easy to test and repair. Repeat 2 more times for a total of 3 relearns.This 2000 GMC Jimmy came in with the complaint of no dash lights at night. GM PASS LOCK RELEARN- Ignition to "run" position, try to start and let key return to "run" positionĪpprox ten minutes security light will go off Perform a relearn on the key first, maight save some work. To verify, with the ignition switch in the run position, test for battery voltage at the appropriate fuse listed below.Īfter IGN switch replacement, VTD (theft deterrent) relearn must be performedĪlso, GM has a bulliten out about thier connectors, you may need to have a look at the cluster connectors and pins, ceck for bent or pushed out pins in the plugs. Most likely cause of this condition may be a loss of power to the transmission on circuit 1020. Techs in field report IGN switch failure is common & may cause multiple symptoms with trans, IPC or other IGN feed circuits. Malfunction indicator lamp (MIL) on, trans stuck in 2nd or 3rd gear, instrument cluster inoperative (diagnose & replace ignition switch if necc).
