No crank when freezing

[Justin Flynn]

Weird issue with my truck. When the truck is parked in freezing temperatures overnight, it won't crank or start, and the dash will have stabilitrak, steering assist, and trailer brake errors. If I blow a heat gun or hair dryer under the dash for a couple minutes, it will start. I've already had the BCM replaced and it didnt fix it. Has anyone had this issue and had it fixed?

 

I've now done the hair dryer trick 4 times with success, but it has left me stranded at work as well as street parked in a city, so I'm almost to the point of selling the truck and buying a Tundra.

You didn’t mention year or model, but still seems like a grounding issue. Mine (2018) used to behave similar but not from cold. I could open the hood and short out between the negative battery terminal and the body with a large screwdriver. It would then start up and work fine. I replaced the ground cable, did a “big three” upgrade of power/grounds, and checked the dashboard grounding point (up by driver’s side a-piller). Haven’t had trouble since. Good luck.
