On my 2010 LT the lever will not lock in the left position, the signal light works but I have to hold it down. The cancelling will not work on the right most of the time. Looks like I have to replace the switch. Does anyone know the correct GM part number? I searched and I did find a thread on how to repair but alas no replacement part no.
Thanks
Ron

I use the AC Delco D6254E

 

I bet you could get one from any parts store that deals Dorman. FWIW: it's called a multiswitch.
GM #20940099
ACDelco #D6254E

Here is one on eBay:
