Screenwasher Jet heaters

sbmcd · Jan 17, 2023

My Call has had a rodent issue at the and vent intake and the cables joint to the bonnet have been eaten along with the screenwash hose, I've repaired the hose but there are cables which appear to run to go the nozzles in the screen easy jets, looks like to some heaters in the nozzles.

These should come on when you switch on a heated front screen but since my Call does not have a heated screen are these cables redundant?

No, not redundant. Heated washer jets were/are standard.

I thought they activated with the screen wash. Designed just to clear a frozen nozzle.

Yes just the nozzle. The water is not heated in the bottle.

Thanks, discovered the circuit is energised when you switch on the heated mirrors. After 8 years of ownership still learning new stuff

This time of year you need a really strong de-icer concentrate mix. I have 50:50 at the mo.

Thank you for that, I tested the circuits with the mirror heaters switched on / ignition on and assumed incorrectly the the voltage that was present was because of that. And you are right I should have checked the manual.
