Keep in mind that the wipers/washers are GEM
-controlled in the 2001 Rangers.
If the wipers do not work at all, the probable source of the problem is either:
. Central Junction Box fuse 16 (30A)
. Multifunction switch
. Wiper run/park relay
. Wiper HI/LO relay
. Wiper motor.
To walk through the troubleshooting steps to determine the source of the problem, you'll need access to a New Generation STAR (NGS) Tester [418-F052] or equivalent diagnostic tool, and carry out the testing steps indicated in the 2001 Ranger Workshop Manual.
