All fuses are intact.

From haynes manual it appears as if the only thing that should be common to the two systems is the ground. Otherwise it could be the Heater control module which could be causing a ground issue.

Does anyone know if there is a common grounding point inside the car. It is just too cold out to tinker around for extended periods of time.

Does the ford service cd have a description of what those relay looking things are in inside fuse box. Thinking one of those might be a problem, if so can someone post an image of that I don't have the service cd. AS well if the cd has a location for the heater control module.

Thanks
