The other day my power door and power seat stop working. I check the fuse on the driver side and it was ok . But there was still no power when trying to use power door switch.
Power door locks and power seat on 2001 Ford Explorer
Fuse number 18 (25 Amp) in fuse box inside the car gives power to both the door locks and power seats. Use a voltmeter to check for the presence of power at both sides of the fuse. Or remove the fuse and check for continuity.
