I have just got a ML320 W164 and front and rear wipers stopped working I have checked the fuses nothing. Does any one have a diagram for the wiring and which relays to check.
 
Stalk failure is very common.
 
Hi sorry forgot to say have fitted new stalk.
 
STAR diagnosis would be the way to go. I doubt front and rear would share the same relay. the common function being the stalk..
 
Nearest one 110 miles away front has two relays and one for rear I am led to believe
 
Tested all relays front and back boxes re checked fuses all good.

Any help appreciated

Obviously you're not testing the wipers with either of the front doors open?
 
No all doors, boot, and bonnet shut engine running.
 
Thanks will give that a try
 
No everything else working.
 
Hi Dec thanks I will get a look at them tomorrow.

Check your door pins are good by watching the interior lights when you open/shut each door.

If it thinks a door is open it halts the wipers.

Thanks will try

Hi tried all things still no wipers cleaned front sam connections as well but nothing.

Thanks

Could the front wiper mechanism/linkage be stuck, this would cause the wiper motor to cut out if it felt resistance, get someone to turn on the wipers while you listen outside for any sign of noise from the wiper motor.

It may be that the rear wiper doesn’t work if the front wiper is not already on.
