Expert:  FIXITMAN replied 2 years ago.
Thankyou. Just so I can make sure that I have the correct schematic, is your car a V6 or V8 model?

Hi bobby i was wondering if you received my last message about my cts being a v6
Expert:  FIXITMAN replied 2 years ago.
I did get it. Sorry for the delay in getting back with you. I would recommend testing for voltage at the turn signal lever connector. With everything hooked up see if there is power at the light blue wire when the switch is turned to the left. If there is not then the switch is bad. If it does then you more than likely have a failure in the body control module, this is assuming that nothing on the left side turn signals work.

I ran a check on the lever/switch itself it was the second or third pin cant remeber but when i flipped the lever to make the right signal we had current and also to the left. I didn't test the harness itself but i did see the light blue and white wire. If there is voltage then i am assuming it is ok. Where is the body control module?
Expert:  FIXITMAN replied 2 years ago.
Yes, that is correct on the test. As for the module it is located under the driver side of the dash on the side of the center console. See if the connections there are clean and tight.

Just for reference what BCM number is ***** I see here that there are about 6 of them which all have a fuse in the engine compartment
Expert:  FIXITMAN replied 2 years ago.
The BCM is a single module that contains many circuits. That is why there are a lot of fuses for it.
