Wipers rain detection does not work
Hello.
Wipers switch has 4 positions : 0="Off" ; 1="Intermittent" ; 2="Speed 1" ; 3="Speed 2". "Intermittent" is also the automatic mode, using rain detection.
On a Vito year 2010, I've automatic lights and wipers. When I put the wipers on intermittent/automatic mode (position 1), they wipe only one time and won't wipe again even in a heavy rain. Positions 2 and 3 (speed 1 & 2) work fine. Spray works fine too : I get a squirt of water and a couple of wipes.
Since the sensor is the same for rain and light detection, I want to specify that lights on automatic mode work fine, during a day with sun they stay off until the night begins. To be sure I've put my hand on the sensor (just below the middle inside mirror) which turns the lights on, lights turn off as soon as I remove my hand from the sensor.
I've undserstood, maybe misunderstood, that when the sensor is broken wipers wipe non-stop (if sensor is broken just wipe). OBD2 does not give me any error code (tried several apps on Android with a Wifi OBD2 plug and even a real diagnostic tool).
What is my problem ? How can I fix that ?
Sorry English is not my mother language.
Thank you in advance.
