When it turns to cold weather, my truck wont start. I turn it on and theres no click then it try to turn over but wont start. It happened last winter also. I took it to my mechanic and they played with some wires and it started. Not sure which wires did it so they sent me home. Worked fine for 11 months. Replaced the radiator and fan last week because I had no heat. Now the heat wont work in the am but works fine in the afternoon and pm. Assume electrical.

Welcome to the forum, if sometimes the starter won't crank, check the circuits at the starter relay. Is it on the fender lining?

One large cable from the battery, the other goes to the starter. A small wire, red with lite blue tracer, comes from ignition switch throught the neutral switch. when trying to crank, that wire should be hot? Have you tried cranking in neutral, when the problem occurs?
