Another Non Functioning Front Screen Washer Pump!

[matt g 5]

Hi all. Any help would be greatly appreciated.

My front washer pump is not functioning when I pull the stalk. The pump is new and works when connected to the battery. When you pull the stalk the wipers operate as they should but no pump!

With a volt meter connected to the pump wires ( disconnected from pump) it shows around 5 volts and then when you pull the stalk it shows 12 volts. When it's all reconnected pulling the stalk does nothing and the volt meter shows no voltage to the pump wiring!

Tried cleaning the earth in the earth block and fitting new spade connectors to the pump but still nothing.

Any ideas greatly appreciated

 

Cheers

The wiring has probably corroded, you'll need to cut it back until you find bright shiny copper then splice new wire in.

Check the earth block to, it's bolted near by to the body.

Hi guys. Thanks for the replies. The earth connection is good. I cleaned all the terminals this morning. ( took a while). The new spade connectors are straight onto good bright wire too.im thinking a short in a wire somewhere hence the 5 volt reading. Maybe?

You could fit a relay into it. Use the existing feed to operate the relay coin and connect a 12v supply via the contacts to the pump.

It is wired through the fusebox from what i remember, so maybe trace the cable back along and checkout the fusebox.

I had this issue before and it was the stalk. Try a 12volt test lamp at the stalk, as you may have voltage, but very little current flow.

Or perhaps split the circuit using amp setting using the meter.
