My husband has a 2002 Ford F-150 Supercab, he has the truck into two different repair shops with no luck. They hook it up to the computer and say there isn't anything wrong or the part has already been replaced.
Whenever it rains the truck will be dead in morning. If he unhooks the battery. And hooks it up when he is ready to leave. No problems. We have also gone to the truck after rain and the blower will be running. We think somehow the blower wire is making contact (through the rain) to a nearby hot wire. Hence. It rains the wires connect. The blower runs. And we come out to that or it runs long enough and drains the battery. We were going to trace the wires and were wondering can anyone lead us in the right direction? We are looking for the blower power supply wire. Where is it located. What color is it? Anyone have any advice?
