Have just fitted new pump, no joy. Wipers working.

Hi there good evening to you and sorry for the delay in responding

ok the system uses a switch polarity system to operate the pump clockwise and anti clockwise for front and rear washers

this comes from the wiper /washer switch

 

Example - in your vehicle when you work the front wipers the switch sends an earth out of pin 2 (white and black wire)

And a feed out of pin 4 (yellow/black wire )


when you select the rear washers it reverses the polarity on the same pins

 

so you need to check across pins 2&4 for 12 volts when you work the washers either way

This must be the first check we carry out


If you need any further help or technical assistance going forward

please let me know and I will do my upmost to assist you

Hi, yes there's 12v out between pins 2 and 4 with wiper switch reversing polarity.

Hi thanks

ok this rules the switch out as it’s doing it’s job of feeding the pump and reversing the polarity

 

the wiring from the switch runs through connector c810 at pins 11 and 12

Connector c810 is located in the drivers footwell (this may be different on LHD )

It shows it on the same side as the GEM module ( this is the module with 5 different coloured plugs )

I have attached an image of the c810 connector to give you assistance

I can see the GEM but not that connector.

Hi did you remove the footwell trims

Customer: replied 7 days ago.
Removed the facia below steering wheel.
Is it behind trim at left in driver footwell?

Should be behind the lower footwell trim that curves up towards the GEM if not try the other side as there’s a few different diagrams

regards brian

From memory these were prone for corrosion due to moisture ingress

Voltage good at connector, +/- 12v.

Hi thanks

ok you will need to trace the wiring from here to the pump as this is the only connector online of the loom

 

This indicates there is a wiring issue between here and the pump

Check nearer the pump and work backward

kindest regards in advance

OK, will retest voltage at pump. I had the headlight assembly out on the driver's side on Monday, maybe I disturbed something, will investigate when I can.
Customer: replied 7 days ago.
One question: as there is a voltage at those outputs, does that mean the GEM is good?

Hi there good evening to you

the GEM is only used to command the wipers to work when the washer switch is pressed (this uses a feed back from the switch

the switch controls the reversed polarity feed to the washer pump

so if you have 12 volts either way at c810 then the switch is ok and it’s a wiring concern to the pump
