WIPER MOTOR AND TERMINAL FUNCTIONS
Re: wiper motor wiring
(See photo below)


Wiper switch plug:
Black wire = low speed
Dark blue (center) wire = wash
Light blue wire = high speed

The wiper switch wires are ground wires. If you remove the switch and simply jump them to ground, it will make each function work.
**NOTE - for high speed, you have to ground BOTH light blue & black at the same time.

Wiper motor plug:
Yellow wires are hot. One goes to fuse box and the other goes to the other terminal on the wiper motor. (see photo)
Dark blue wire connects directly to the dark blue wire on the switch plug.

( WIPER MOTOR PLUG):
Yellow wire - jumps around to the other yellow wiper motor plug. (see photo)
Light blue wire - connects directly to the light blue wire on the switch plug.

( WIPER MOTOR PLUG #2):
single black wire - connects directly to the black wire on the switch plug
