2011 corvette front indicators work but not the rear

Customer Question

2011 corvette front indicators work but not the rear

1st thing to check is if the lights come on with the hazard switch?

If they do then it must be a fault with the indicator stalk or possibly the body control module

if they don't come on with the hazards then I'd say that the fault must lie with the rear wiring loom, so remove the trunk / boot carpet and trace it back into the car, checking for chafing and damaged wiring

rear indicators don't work with hazard lights and all wiring looms look secure
Could not find any fuses for indicators do they go through body control module? and if so how is that checked?
Expert:  Matt replied 1 year ago.


the body control module should have its own fuse and sorry to say the only way to check that module is with a dealer level scan tool

this can run a diagnostic and check the CAN communication around the vehicle which I'd say is probably going to have to be the next step

it would also be worth checking the connector plug to the BCM it should be behind the passenger floorboard. Just pull the panel back and you'll see the BCM and the stereo amp.
