Frequently asked questions

What does Screen Washer Pump ADU3905 do on a Land Rover?

The ADU3905 is the rear screen wash electric pump that draws washer fluid from the reservoir and delivers it under pressure to the rear wash jet when activated. It's the rear circuit pump only, not the front screen wash pump. It fits Defender (from VIN AA270226, 1986-2006), Discovery 1 (to VIN LA081991), and Range Rover Classic (all).

Which VIN range does the ADU3905 Washer Pump fit on the Defender?

On the Defender, the ADU3905 fits from VIN AA270226 onwards. Defenders before this VIN may not have a rear screen wash system or use a different pump configuration. Cross-references are STC1453 and RTC3959.

What are the signs that the rear washer pump ADU3905 has failed?

A failed rear washer pump typically shows as no fluid reaching the rear screen when activated, while the reservoir has fluid. A working pump usually hums briefly when operated. No operation at all, or a pump that runs but produces no flow, typically indicates pump failure or a blocked feed line.
