W209 CLK headlight washers not working

[cobra2222]

hi all,

got a strange problem with my headlight washer system, they dont work when i press the button so took the washer pump out tested it on a 12v psu and it worked, put a meter on the car washer connector and noticed it has a constant 12v then increased to 15v when the button was pressed. i can feel the car engine and rev counter go up a little when the button is pressed but nothing happens, have also manually moved and loosened the jets. any ideas??

If it is anything like my C209, CLK they will only work when the headlights are switched on. It took me a while to learn this.

Get it on a Star. Read the switch values. That's the only way really

The pump has to operate at a high pressure to first push out the was nozzles and then the fluid.

Gently pull out each was nozzle while someone operates the switch to make sure they are not stuck. It could be the pump is just weak. It is an easy change from under the wheel arch.

Same problem as mine, I got a replacement pump off Ebay for £16, not fitted it yet but apparently this is a common problem on the 209's.
