Last week on the way to work, I pulled over for gas. When I restarted my car, my radio and clock reset. When I got to work, I turned off my car, then tried to start it up again to see what happened. It wouldn't start, seemed like a bad battery.

When I left work, it started fine, and I made it home. But y'all know how when you open and close your door the window pops down and up a bit. It came down, but didn't go back up.

This happened to me last year, and I changed out the alternator and battery. I took both to be tested today, and both were fine. I have no aftermarket electronics and only added a K&N intake. Any suggestions of what the issue could be?

 

My buddy had a similar problem, turns out the connection to his battery connectors were loose and occasionally losing contact with battery terminals.

I would say check your lines but aside from that I couldn't say.

 

That happened to my wifes truck, but it wasn't loose, there was an actual break in the battery termal caused by acid corrosion. I was pulling my hair out trying to find the problem.
