Well when I turn on the blinker and then make a turn it never turns off by itself. I have an aftermarket steering wheel, could this have anything to do with it? any way to fix it? thanks.
theres a tab in the hub that should turn off the signal, yours is probably not hooked up properly or it doesnt have one.
yup spilner is right u need to make sure u didnt take out the spring that kicks in and out the signal when u changed ur wheel and u goota make sure the hub u have came with the extension part
well I didn’t do it, this steering wheel has been on the car for a long time, some previous owner did it.
So how do I check if it’s there or not? Would you guys be able to tell if I posted pics ?
yup for sure just take the wheel off should be jsut six screws and take pics of it 
and the outside casing of the hub where it hits ur steering shaft
this site should help you out
the previous owner probably didnt modify the hub to accomodate the signal cancel
