fuse layout engine bay fuse box

[mck684]

hi, to try and fix my windscreen washer pump sprayer not working (no power to it atall even though the wipers work-lights sprayer works though) i am checking all fuses. the book says nothing about a fuse for this pump. is there one? i opened the fuse box by the battery and found a loose fuse on its side not plugged into anything, could this be the culprit? thing is i dont know which fuse socket it came out of, has anyone got any info of what fuse does what in the engine bay fuse compartment? many thanks,

car is 2003 172 by the way...

This might help?

 

[mck684]

that was quick! thanks ill check it out this morning... is that a pic of a 172 (non cup) just concious that cups may have less fuses...

 

[DannyR]

That's a 172 Ph1 so there will be one less for ABS in yours!?

 

[mck684]

yep mine looks exactly the same, i can only imagine someone left that fuse in there by mistake when replacing one etc.

cheers

Fairly sure the washer one is in the passenger side for it. It a square or window screen shape with a fountain of water in front of it

Similar without the heater bits

ta, i checked the book and there is one for the wipers and the headlight washers but not the windscreen washers! i was under the same impression they use the same pump (wiper spray and lights spray). maybe the windscreen washer pump is not fused?

 

[DannyR]

It is the same pump that does both yes.

Checked for blockages?

Can you here it whirring when you pull the stalk?

 

[mck684]

no, no whirring. it started playing up -working intermittently a while back but now completely stopped. I thought the pump was on the way out but it cant be as the lights spray works strongly. when you pull the lever in the cabin the wipers do 3 wipes but no spray.

 

[DannyR]

Well it's the same pump that does the lights so it should whirr if the light ones are working

I'd try getting a multimeter in the plug and seeing if it reads 12v when you pull the stalk, if it does then its the pump

It isn't actually, there's two seperate pumps. One does front and rear windows another one does headlights.

Also the headlight washer pump, is timed by the UCH. It will only power up if the lights are turned on and the windscreen is washed.
The fuse for the windscreen washer pump is not in the engine bay either, it is on the side of the dash with the others.

If the pump has slowly stopped working for the windscreen, I'd say you need a new pump

 

[DannyR]

Well I never knew that, as people had posted on here asking for a pump with extra take off for lights

what does the small 30 amp green one operate on top left?

thanks

Could the stalk on the squib be a cause? It's not the pumps

Bump

I've seen the contacts in the wiring plug be at fault before, they've shown a good 12v feed but no power was getting to the pump at times, cut off a plug from a donor car and connected it up, had no issues once I'd changed the plug

They're showing a good 12v when activated, do you mean the plug that goes into the washer motors

Yep the plug that connects to the washer pump, connections were playing up. As I said I soldered on another plug and all was fine afterwards

I found the problem, it was in the engine bay fuse box. Took them out and cleaned them now everything works fine
