Washer Pump Fluid Pressure Low Test

  1. Check that washer fluid hose is not kinked, clogged or leaking. Check for battery voltage between wiper module connector cavity "A" and junction block connector cavity "C8". Voltage should be present with ignition switch in ACC or RUN positions, and column switch on WASH. If voltage is present, go to next step. If no voltage is present, repair open or short in circuit No. 94A (Pink wire).
  2. Check for battery voltage between washer pump connector cavity "A" (Pink wire) and junction block connector cavity "E6". Voltage should be present with ignition switch in ACC or RUN positions, and column switch on WASH. If voltage is present, go to next step. If no voltage is present, repair open or short in circuit No. 94 (Pink wire).
  3. If washer fluid pressure is still low, replace washer pump and verify proper fluid pressure.
