Did you perform the Diagnostic System Check - Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle

Verify that the turn signal lamps and/or indicators are inoperative.

Do the turn signal lamps and/or indicators operate normally?

Go to Testing for Intermittent Conditions and Poor Connections

Go to Step 3

Are only the turn signal indicators in the instrument panel cluster (IPC) inoperative?

Go to Step 4

Go to Step 5

Test the inoperative turn signal supply voltage circuit to the IPC for an open or high resistance. Refer to Circuit Testing and Wiring Repairs .

Did you find and correct the condition?

Go to Step 21

Go to Step 12

Is only one turn signal lamp inoperative?

Go to Step 6

Go to Step 8

Test the inoperative bulb or tail lamp printed circuit board for an open or poor terminal contact. Refer to Circuit Testing .

Did you find a condition?

Go to Step 18

Go to Step 7

Test for the following in the turn signal lamp supply voltage circuit or an open or high resistance in the turn signal lamp ground circuit. Refer to Circuit Testing and Wiring Repairs .
