Electrical problem
1995 GMC C2500 V8 Two Wheel Drive Automatic

My van's blinkers do not self cancel. And this is an inspection item. I wan to do the work myself and replace what I need to. I got the parts to do it, but still not sure what to do. Can you give me step by step instructions what to do? I know my steering shaft/column needs to come out and it is bolted. But after that what do I do? And how do I know if I have put the steering column back in properly?
Thank you.

I will step you through the process if you still need help let me know.
