Michel
Well how about that, I had already, by your name, assumed you were French I am a Brit but we will not hold that against each other as we both are passionate about JAGS AND THATS ALL THAT MATTERS,

David,

Not only we drive the best cars in the world, but our forums are fantastics and our clubs are second to none. I had by mistake driven and owned some MB's in my life , of course I had more issues with them then with the Jaguars. Do you know that there is no help from the forums there, may be for the first SLK with all the problems, but after that forget it we have a MB and we take it to the dealer to get it fixed regardless of the cost. They are missing the best of all ; our camaraderie ( Hey I am French and this looks English to me) I am a strange one (French)

Cheers and thank you again

Michel

Thank you again, members you are great!

Hi Michel,
From the main instrument cluster, the wash level input is fed by an orange/red wires which terminate at the yellow wash level switch/relay which is also grounded, must be a good ground. The entire instrument warning light system is fused, hot at all times, by 2x 5amp fuses found in the left fuse panel. Check all of this out, sorry that I cannot pinpoint your problem.
Good luck
David H

Hello Steven,

Yes I removed the top portion of the reservoir only. I will try to clean the relay and the wire as suggested by David and if the light is still on then I will remove the complete unit from the bottom.

Thanks for your help

Michel

Hello David

Sorry about that, it is a 1990 with only 43k miles, I already cleaned the relay contacts, i will do it again just in case. Where will I find the wire?

Thanks for your help

Michel

Did you remove the complete reservoir, or only the top portion? The bottom portion is the part with the level sensor in it. It's only accessible from the bottom. They are joined with an "O" ring seal where it passes through the body panel behind the headlamps.

Cheers,

Hi,
You do not mention the year of your XJ40, yes there is a wash level input and a wash level switch wire color code ORG/RED. There is also a W/S wash relay colored yellow mounted in the right hand side under the hood, however I would suspect a grounding problem check that you have a good clean ground first.
Best of luck
