Did you change both fuses? There are 2 one is F1-24 located in fuse box under the hood. The other is F2-26 located in fuse box passenger foot well on the wall at passenger's right foot.
Next is to know if the pump is getting battery voltage. Key off, disconnect C137 at the pump. Key ON, measure voltage on pin one wire color is red/white Voltage is read while pressing the multifunction switch to the wash position.
Voltage must be greater than 10 v.
Got 10+ volts? YES then check other wire in same plug, black/ white wire to ground. Should be less than 5 ohms. Got it? NO repair the wiring. YES needs a new pump motor.
IF there isn't 10+ volts at the pump plug then you have to dig deeper.
Key off disconnect C110 at the
wiper motor up by the windshield. Measure the resistance between C110-4 to C137-1. Resistance should be less than 5 ohms. NO repair the wiring.
YES check for correct
wiper motor operation. Operation not correct, needs new
wiper motor.
Operation correct retest
washer pump.
All okay ? Could have been loose pins or corrosion
Note:
wiper motor can bind up during operation, it will turn itself off which also shuts down
washer pump. Binding can come from
pivot arm being out if adjustment.
Hope all of this helps.
