The Washer spray thing and the wiper delay quit working. I checked fuses nothing blown, also checked for power at the washer pump - no power when I have someone press spray button..

any ideas on where to start looking or literature on how to get this resolved would be much appreciated.

So friggin big!
My credo
Give me money.
I'd pull the stalk (multi function switch) and test that if the fuses and relays checked ok.

According to this diagram Delay and washer share the same wire to the GEM from the multi-function switch

All the wiring in the GEM and switch are GROUNDS, and GEM controls the Relays that activate the washer pump or the Wiper motor.
The fuses power the relays and devices

So when you press the Washer button that sends a full time Ground to GEM on the Washer wire, light blue/orange wire
The GEM then Grounds the washer relay to activate the pump, in relay box #2, not sure where that is???
GEM would also Ground the wiper motor relays to active wipers while washer is spraying

When you select delay wipers the switch sends Ground but thru a 3.3k resistor on that same light blue/orange wire

Washer relay could be bad but that wouldn't effect delay wiper function

Do the wipers come on when you press washer button?
Or does nothing happen

GEM = generic electronic module
This is the Body computer in Rangers from 1995 to 2003, its located behind the radio
All the switches in the cab, except main headlight switch, are controlled by the GEM
When you select 4WD the GEM gets that signal from the 4WD switch and activates the 4wd
When dome light comes on GEM did that
Wipers are no different, wiper switch isn't connected to wipers or washer, its connected to the GEM
