There is a electric motor that pumps washer fluid . Located in the bottom of the washer fluid tank .
Wash Operation (Front and Rear Wipers)
The front and rear washer systems use the same windshield washer fluid pump. When either the front or rear wiper is in the washer position voltage will be supplied to one side of the windshield washer fluid pump (depending on whether it is front or rear), while the other side of the pump is grounded.
At this point, the windshield washer fluid pump sprays solvent onto the windshield. When the front or rear washer is activated, the BCM receives an input from the switch that is activated. The BCM will control the wipers while in the WASH mode. The BCM will control either the front wiper relay or the rear wiper relay to turn on the wipers. The windshield wipers operate at low speed for 3 swipes and returns to the park position.
When turning on the washers do you hear the motor run ? Have some one try it while you listen at the washer fluid tank ! These pump motors do go bad .
turn OFF the ignition.
Disconnect the harness electrical connector of the windshield washer fluid pump.
Connect a test lamp from the windshield washer pump control circuit to a good ground .
Turn ON the ignition, with the engine OFF.
Press the front washer switch.
Does the test lamp illuminate?
YES or NO !
no same tank but two pumps possible clog of line and or nozzle pull hose off nozzle and try to see if fluid squirts if yes use a pin or air or clear nozzle if no fluid possible pump in washer fluid tank shot
Can you hear the (washer) motor run? Have someone hit the squirters with the key on and out your ear to the filler tube to see if you can hear the pump running. If yes, common for the impeller to spin off the shaft of the motor. I have found that the replacements at the auto stores work rather well. Something of a pain to remove the tank though!
sometimes there is, and sometimes there isnt, if there is one it will be on the bottom of your windshield washer tank.. sounds like they fed you a line of **** to me... and if they arent i would take it back and ask them why its doing it again, and why they didnt clean the tank out before... theres something else going on.. either a leak in one of the hoses, your low on fluid, or the pump is weak... i think they fed you a line.. hope this helps
