Intermittent windshield wiper doesn't work; wiper stop mid glass

Wd40 of gt85 tray that first

When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper motor until the wipers reach the park position. If the ignition is turned off while the wipers are in mid-cycle, the wipers will stop immediately where they are. The wipers will park the next time the ignition is cycled to the ON position.

The Wiper / Washer System consists of the following components:
?€¢
Windshield wiper / washer switch

?€¢
Windshield wiper system module / motor

?€¢
Windshield washer fluid pump

?€¢
Windshield washer fluid level switch

?€¢
Instrument panel cluster (IPC)

?€¢
ACC 15-amp fuse

?€¢
WSW 30-amp fuse

If the wipers self-park in the other settings and after use of the screenwashers the fault is probably in the intermittent timer relay or circuitry.

If the self park is not working in the other settings the fault is probably the self-park switch within the wiper motor.

Yes that is likely a switch problem. Before you buy any parts have a shop confirm my guess.

hi there . think they may need a bit of wd40. spraying on the shaft.
probably just road dust and debris. making it stick.

Hey Anon,
I just finished replacing the intermittent (wiper motor pulse board) control on my vehicle.. it was doing exactly as you describe.. it wasn't hard.. just time consuming..

most likely cause is the wiper switch has gone bad and unable to 'time' the intermittent speeds.the intermittent speeds work on a resistor type system where low and high speeds add direct voltage.

sounds like you have a bad multi function switch ( the wiper switch that is also a turn signal switch)

2002 Windstar wipers would come on by themselves, or not work set on intermittent, driver door lock would not work sometimes, ABS and brake light would come on sometimes, the problem was in the park switch inside the wiper motor. I replaced with wrecking yard wiper motor $44.95 w/13 month warranty. no more problem. check how many pins on connector plug, mine had 5 on the wiper motor side.Take the wiper assembly off of the metal cowl, 2 nuts, & I bolt, it is easier to snap the actuator pieces off of the wiper motor that way. God Bless JMR

You will have to change the swich that control the wiper blades cause sometimes they go bad
