12 | Using a test lamp, check junction block 1 turn/hazard flasher cavity 2 to ground. Does the test lamp illuminate? | Go to Step 14 | Go to Step 15 |
13 | Replace the hazard switch. Refer to Hazard and Turn Signal Flasher Replacement in Instrument Panel, Gages, and Console. Is the repair complete? | Go to Step 23 | -- |
14 | Using a test lamp, check junction block 1 turn/hazard flasher cavity 3 to ground. Does the test lamp illuminate? | Go to Step 16 | Go to Step 17 |
15 | Repair the open in the flasher feed circuit between the junction block 1 turn/hazard flasher cavity 2 and fuse and relay block 1, C5 cavity 3. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | Go to Step 23 | -- |
16 | Using a test lamp, check junction block 1, C4 cavity 1 to ground. Does the test lamp illuminate? | Go to Step 18 | Go to Step 19 |
17 | Replace the turn/hazard flasher on junction block 1. Is the repair complete? | Go to Step 23 | -- |
18 | Using a test lamp, check the hazard switch cavity 4 to ground. Does the test lamp illuminate? | Go to Step 13 | Go to Step 20 |
19 | Using a test lamp, check the junction block 1, C6 cavity 5 to ground. Does the test lamp illuminate? | Go to Step 21 | Go to Step 22 |
20 | Repair the open in the GRN/WHT wire between the hazard switch cavity 4 and the junction block 1, C4 cavity 1. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | Go to Step 23 | -- |
21 | Replace the junction block 1. Is the repair complete? | Go to Step 23 | -- |
22 | Repair the open in the GRN/WHT wire between the junction block 1 turn/hazard flasher cavity 3 and the junction block 1, C4 cavity 1. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | Go to Step 23 | -- |
23 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 3 |
