Re: Need someone experienced in ford windstar electrical
It's tough to tell, the circuits will travel in the same loom through the harness. The first thing I'd do would be a physical check, basically a hand over hand with a flash light, looking for corrosion\deterioration at terminations and anything wearing through the loom. If nothing shows up, check voltage going to the sensors, it should be about 5 VDC.
