CFT, I had the same problem with my 2008 Chevrolet Colorado. Sometimes it just would not do anything. I have heard this attributed to the security system among other things. That is the reason I traded it for a new 2012 Ford Escape in late 2011. I have a friend who had a 2002 Chevrolet S-10 with the same problem. He replaced it with a Toyota Tundra. I was a General Motors fan for sixty something years. No more.

The more I listen,the more I hear....and vice versa.

45/70,it's almost a religion.

If you have to take a second shot then you probably shouldn't have taken the first shot.
