1. Place the headlamp switch in the OFF position.
2. Remove the Instrument Panel Cluster (IPC). Refer to Instrument Cluster Replacement in Instrument Panel, Gages, and Console.
3. Probe the headlamp high beam supply voltage circuit of the high beam indicator, at the IPC connector, with a test lamp that is connected to a good ground.
4. Place the headlamp switch in the HEADLAMP position.

Does the test lamp illuminate?

Go to Step 4

Go to Step 7

4 | Connect the test lamp between the headlamp high beam supply voltage circuit of the high beam indicator, at the IPC connector, and the high beam Indicator ground circuit at the IPC connector. Does the test lamp illuminate? | Go to Step 5 | Go to Step 8
5 | Inspect the high beam indicator bulb for an open filament or poor connection. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 10 | Go to Step 6
6 | Inspect for poor connections at the harness connector of the IPC. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 10 | Go to Step 9
7 | Repair an open, high resistance, or short to ground in the headlamp high beam supply voltage circuit of the high beam indicator. Did you complete the repair? | Go to Step 10 | --
8 | Repair an open or high resistance in the high beam indicator ground circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 10 | --
9 | Replace the IPC. Refer to Instrument Cluster Replacement in Instrument Panel, Gages, and Console. Did you complete the replacement? | Go to Step 10 | --
10 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 3
