Turn Signal cancellor broken - 89 Burb

Hi, I'm new. I got an '89 burb with a few problems here is one of them.

After a left turn the signal won't cancel. It will cancel after a right turn. What all is involved in fixing this? What parts/part #'s? Price? I can get my hands on a steering wheel puller from autozone but have never actually pulled the wheel, any tips on that? What is the dissassemby process like?

You will need to remove the steering wheel and the lock plate (you will need a puller for the wheel and a compressor for the lock plate)
There are 2 coiled springs on the turn signal assembly (one cancels right, the other left) they just snap in...I would suggest replacing both

Don't know the part number, but they are fairly inexpensive and available from your GM dealers parts department
