Advance trac light comes on for no reason and will go out for no reason

Asked by for the 2007 Ford Explorer
The two problems would be unrelated.Usually if the blower motor only works on high the blower motor resister has failed. It's in the center of the dash. Before jumping to conclusions you would need proper test procedures and component locations. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
