Nice to hear from you again. Thank you for requesting me, sorry I was not online earlier. I have a new son... 5 months old and he has been taking a lot of my time :)
Can you please provide the last seven digits of the vehicle identification number? I would like to look up the wiring diagram before suggesting the first step. Thank you.
That is great news about the transmission! Thank you..I love being a father!
330i 11/02 production m54 engine E46....let me see...
The washer pump is controlled by the general module. It looks like it is fed by a 30 amp fuse Fuse # XXXXX This will be located in the glove box. It would not hurt to inspect the fuse first. However, Eric was most likely on the right track. Most often the failure is the pump itself. One thing that you can do to verify this will be to remove the plug to the pump and have someone pull on the wash lever to activate. Using a volt meter you could then check voltage at the plug to see if you see battery voltage (aprox 12v) this will indicate that all is well in the circuit and that the pump is the failure.
The reservoir I think is just held on by 8 mm screws. This can then be lifted up for easier access. The pump is just pushed down into a rubber grommet so you can actually just pull it up and out. You will lose the washer fluid if it is filled so be prepared to catch it if needed.. At that point the connector can be removed to do the voltage check. Watch out for the level sensor on the bottom as the wires are small and the connector can break. It is easy just to unplug the sensor if you want to take the reservoir out. I have seen pumps like this fail due to some contamination in the reservoir so it might be worth removing and rinsing it out.
The part number of a new pump is: 67 12 8 362 154
