2002 Dodge Ram 1500: I have a short that drains the battery in a few days or less. The problem is, it only shorts when it is cold outside. Like (below 35F) or so. When it worms back up, no short anymore. I know how to narrow down where the short may be, using a test light or multi-meter and pulling fuses. But that is only when it is cold outside. I live in Dallas so it may not get that cold again. What would cause this, only in the cold stuff? So is there a way to trace/track it down any other way? Or am I stuck waiting until next winter? lol Thanks in advance
