Yesterday I had 2 start up a couple hours apart where I got a click and then nothing, both times. It took 2 more try’s both times doing the same thing until it finally turned over. This morning went to go start my truck and same then went to key over and nothing except one click when I first key over. Pulled my battery and took it to Napa to get it tested thinking that’s a good place to start. I hade 710 out of 850 of cold cranking amps. And the reader said the battery was good. Put the battery back in and went to go try it again, it did the same thing were I got a click on the key over then nothing, then on the dash said roll window down then up, after doing that it started right up, and ideas?
