If fuse is okay, check for open in Yellow wire between connector C201, terminal E9 and FRT WPR/WSHR fuse terminal in fuse block. See WIRING DIAGRAMS . If fuse is blown, check Yellow wire for short to ground between connector C201, terminal E9 and FRT WPR/WSHR fuse terminal in fuse block. Repair as necessary and retest system. 3. Turn wiper/washer switch to HIGH position. Using test light connected to ground, backprobe wiper switch connector C201, terminal E4 (Purple wire). If test light is on, go to next step.
