Its a 2006 jetta tdi/brm. It doesnt pump any fluid.
I have a Bentley manual. I am good at reading wiring diagrams for American cars, but i cant make heads or tails out of the german diagrams. I did find that the washer pump is on sc42. I opened up fuse panel C on left side of inst panel and found sc42. Its 15 amp, not 20 amp as the Bentley shows. There is a Block with no internals shown identified as the vehicle electrical system control module, but there appears to be no schematic of this module itself. Or any info as to location. Why would a ton of accessory fuses go through an electronic module? They are just ignition key relay enabled loads off the battery, are they not? The little tiny piece of the diagram showing the washer motor itself was of no help, it could not trace power back to switch and fuse, or back to a battery bus.
I checked SC42 15 amp with test light, it did not illuminate. I checked both sides of fuse with dmm, and its at 3.6 volts. I am definitely on right fuse because when i actuate the washer switch, it drops to .4 volts. This is telling me that the switch is working, and also that the motor hasnt burned out/ open-circuited. Its telling me that there is a resistive connection somewhere between the battery bus and the fuse. But i have nothing showing this path so that i can trace it down to the bad connection. Ideas?
