RE: Help ..Fan has gone Haywire
At 20°f the a/c or defrost shouldn't naturally turn the fan on. Especially if the truck is moving.

Signature620 has the right approach. You need to know what switch, fan solenoid or temp sensor was commanding the fan on. Also inspect the fan hub for air leaks or mechanical problems like a bearing starting to fail.
