So

perhaps you good gentlemen can help

I have recently acquired a Mondeo (no that isn't the problem).

The rear washer has never worked properly, and for the first couple of
months a small amount of water would just trickle out until after a couple
of seconds a short squirt of water would come out of the front washer.

After a few weeks of this, the last time I used it all that happens is it
squirts water out of the front washer exactly like I had operated the front
washer (except that the wipers don't come on).

What is going on here?

How many pumps does this sort of system have. How is the water routed
between front/back?

(and is this an MOT failure! - probably too much off topic!)

TIA

No; the rear washer/wiper is not part of the test.

Almost certainly a valve has failed inside the pump. Ebay for a new one.
should only be a few quid. Press fit into the tank.
Access to the tank? all depends on the car. My Cmax has the tank in the
wheel arch so as and when I need to, I'll approach from behind the arch
liner as a first attempt

Most pumps output from one pipe when turning in one direction and the
other outlet when run in reverse.
Valves & pumps usually killed by running with empty tank - the pump
needs water as a lubricant.
Rear wash/wipe is not part of MOT but the front is.

Wiggle a needle down the tiny hole on the back washer jet - it's highly
likely to be a build up of slime or a bit of gunge blocking the hole.
Have someone operate the rear washer while you stay at the back and do it 3
or 4 times to see if it dislodges, also when refilling the wash bottle, add
a few drops of household bleach to the water to prevent slime and algy
building up in the bottle

Nozzles block with limescale, remove and soak in vinegar.
The pipes can break where it flewes at the entry into the bonnet or
boot lid.
The pump also gets blocked with gunge, remove and clean.

The nozzle is blocked.


I had credited the OP with enough intelligence to have tried that
already when I wrote my reply lower down but I suppose you could be
right and I was being naive?

Never assume anything.

TBH, it only occurred to me because the rear washers on my car were frozen
yesterday but the front ones weren't and when I pushed the rear washers,
water came out of the front ones...

Originally enough water came out for me to know that it wasn't completely
blocked, but in the current conditions I have no idea whether it is frozen
somewhere along the line, unlike the front there's no access to the pipework
to the rear.

But I did wait until the end of my two hour drive last week, after every
other piece of ice had melted off the car before trying, but it could still
have been frozen.

But I wanted to know if this coming out of the other pipe was "normal".

I guess I'll have to wait until spring to find out if it's blocked.

thanks everyone

If it's frozen somewhere under the trim, it will thaw as soon as the
temperature stays above freezing for a few hours - hopefully before
spring! Meanwhile, try pouring some hot water water over the nozzle and
poking a pin into it.
