Hi All, Nothing happens when hitting the windshield wash button in the car. No pump noises or attempts to spray.
I checked all the fuses with a multimeter, and found fuse for the headlight washer was burned out, and replaced that. Now sporadically will have the headlight washer spray(misaligned and for some reason aims at the windshield, LOL). Saw a post about a timer & them only working with headlights on. Looking forward to getting home to try this. Didn't occur to me that could explain them working every so often.

Either way. Nothing from the windshield spray nozzles. On the diagram I found there doesn't appear to be a fuse dedicated to windshield washer or labeled as such. Does anyone know if there's a relay for the windshield washer pump, and which one it may be? or have any other ideas for troubleshooting? Any help is greatly appreciated.

 

Did you try checking for 12V getting to the windshield washers pump?
I had the same issue, verified I had 12V all the way down, replaced the pump itself, and everything was back to normal.

 

Thanks for the reply. I actually swapped the pump with one I found on eBay since i thought that may be an easy fix, but I’ll check for voltage to the pump. It’s possible the used pump was also not a working one.

How would testing voltage work? Someone in the car would need to activate, While I have the wheel off and check for voltage?

There’s no other relay or fuse that specifically handles that pump? Would it be strange the headlight washer pump has a fuse but that one doesn’t.

 

Fuse is F48 (15A) and relay is R7A on the CEM.
Are your wipers moving when you push the button on the stalk or not at all? (The bonnet needs to be closed for the wipers to activate).
Yes, you need someone to activate the wipers while you read voltage on the pump plug.

 

 

You’re a prince and a gentleman. Thank you man. I put my code reader to see if there’s anything helpful there. My thinkdiag had codes for open circuit to ground for rear wiper, rear washer relay and for front washer relay. I’m pretty sure it’s the relay now with this info.

 

I had to replace the pump in the reservoir on my car.

 

Funny enough, I did that with a cheap used one from ebay, but this weekend going to test with a multimeter to see if there's power going to the pump. It's possible the pump they sold me was also defective.

 

Also, I know it sounds trivial, but make sure you replace the pump that is the lowest one on the tank (the top pump is for the headlights washers).

 

That's not trivial actually. I'm going to test this weekend and see if it's needed. How are you guys finding cross over part numbers? The AM part from scuderia is $300 when it's at best a $50 Ford motor co part. Any one know the cross over part number to get from Ford or Volvo?

 

I don't remember a cross over part number, sorry, all I did was looking for the proper connector shape and pins orientation.
I believe it's a Jaguar/Land Rover windshield pump.

 

Jaguar part number: C2C30350 or C2S4065

Genuine part:

I think this is it. Aftermarket one from Eurospare for under $15:

That looks promising, keep us posted!

 

Will do EJ.
This may be the stupidest question ever, but having a hard time sourcing relays for the Aston. Anyone have any idea what relay it is?

 

They're just standard relays, you can use the part number / reference on them to source.
