Your ignition key will not let you pull it out after you turn it off 50 of the time on a 97 Chevy s-10 pick-up 4.3 automatic?

I had a similar problem and did alot of reading. It appears there is an issue with Gm igniton switches. They can cause stuck keys. also can cause vehicle to stop running even while driving (this is what happened to me) SES light, window, wiper and shifting problems. I replaced switch it was a pain as you have to practically disassemble your dash. part cost abt. 100.00 at Autozone. also your key tumbler could be bad very cheap and a little bit of a pain to replace
