Re: 2002 vw golf rear windshield washer
The washer pipe will have blown appart.this happens if you opperate the rear washer when it is frozen.it will either be off in the tailgate usually when this happens there is water around the catch when you open the tailgate.or in the headlining in the left rear,have a feel and see if the headlining is wet.to avoid this reoccuring use a good screenwash with frost protection.

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 !
The switch for the rear wiper is on the actual windshield wiper switch for the front wipers, you have to push the lever forward to turn it on and then again to turn it off, to use the washer fluid for the rear wiper you push the same lever forward and hold it there till the washer fluid comes out.
check that the jet is not clogged.take a very thin piece of wire,like from a twist tie and clean the hole. maybe the hose is pinched or disconnected.if you spray the rear,you should hear the pump working.i have seen hoses come off and if you spray for 20 seconds,it may leak from the car
Try standing outside of the vehicle and having someone press the "juice" button and listen to see if the motor is trying to spray. If it is....check to to see if you have contaminents in the windshield wiper fluid reservoir.
