Thanks for all the replies.
Gilbertd, in the RAVE manual it doesn't distinguish between LHD and RHD, but the image shows a LHD vehicle. That was why I was wondering did it matter which side the driver is on, or is the water reservoir and washer pumps always on the RHS. It seems that it is always on the right.
Thanks, dave3d, that means it's always on the RHS.
The information about the plug colour is useful as, again, RAVE doesn't mention that [I don't think]. I know it shows the location of each pump in the diagram but doesn't mention that they are different colours. I suppose you would soon find out when you get under the vehicle.
I had a look under the bonnet while checking the lack of pressure but I didn't see the non-return valve. Where is this situated, could someone tell me ? I see that the water rubber tube seems to go down the back of the components connected to the fuse board and battery area, but does that mean it drops down to the chassis member and then run forward to the reservoir ? I am thinking of ordering a new non-return valve as I can hear the pump working, although I suppose that doesn't necessarily mean that it is working properly. Maybe I would be as well ordering a new pump as well, just in case.
Lastly, if I can ask - I saw a mention somewhere of removing the foglight cover, to access the pumps, if the bumper bolts are seized. Are the fixings for the foglight on the outside of the vehicle ? Is it any easier than removing the bumper ?
Many thanks for the help. Pierre3.
