Often, but not all the time, I have to play with the turner thing to turn it on (ya know, where the key goes). What I mean is, I have to slowly push it in, pull it out, turn, twist, and nearly resort to nuclear warfare to turn my truck on. It's not a major problem, just a major inconvenience. Is this some kind of anti-theft system, or is something broken??? 79 K5 Blazer Cheyenne.... That's all I have to say about that.
