My van listed above the rear left turn signal quit working. Changing light bulb did not fix the problem. On dash baord, the arrow flash very fast when turn left, but the rear left turn light does not flash.

Can you help me on deciding what part it needs to fix the problem?

Thanks

The fact that the indicator is working shows that the wiring from the switch to the junction block is working. However, the light in the rear not working means it is either the bulb, connection, or wiring. In order to test this, we need to go to the rear and remove the bulb and use a test light to check for power on the wire shown in the diagram. If you have no power on this wire then the wire from the junction block to the bulb is the issue.

Here is a guide that will help testing this circuit:
