Front screen wash spraying instead of rear in Mini Cooper D - MINI Cooper Forum

Hi all,

I was hoping you could help. Today I noticed that the front windscreen wash was spraying every time I used the switch to activate the rear. This is first time I used th washers since getting my 58 reg mini cooper D back from the bodyworks after the bumper and windscreen had to be replaced after an accident in the recent snow. What had happened do u think? How do I fix it? Was it the garages fault and Do I have to call the garage to come fix it? They are so slow! It took three weeks the last time.
Would be grateful for your opinion. Thanks

Hi - yes it's the garage's problem as the fault wasn't on the car when you picked it up - you may have to be direct to get them to take an interest, I find a visit to explain in person the problem will get it booked in, rather than a call or mail that may get fobbed off,

off the top of my head as not familiar with the pump setup - it's either than they had to disconnect part of the loom during repairs (unlikely for a windscreen and bumper) or, the washer pump on a mini does both front and back, they connected the pipes the wrong way round - would make sense if they had to remove the bonnet during repairs?

May be a case of tracing the pipe from the bonnet and see where it ends up, if there's two pipes then swap them round to fix? worth a look to save a trip out and wait for them to get it in

I believe one washer pump on the 2nd Gen does both screens - running one way it washes the front screen and running backwards washes the rear screen - presumably there are quite a few non-return valves in the system.

Our 2008 cooper owned from new has just decided to also show this fault. Front wash wipe performs normal, rear wash wipe sprays from the front and rear at the same time. Any ideas can't be a directional pump as it would be front or back not both. Stuck valve ? But how come front wash wipe function is ok ?

Yep, sounds like a one-way valve has failed, but I think they are inside the pump moulding, so that may need a new pump too. £60 for a bit of plastic and a motor.....
