How to adjust intermittent wiper interval?
 

Is there a way to adjust the intermittent wiper intervals on an 03 ML350? I ran a search but did not find any clues. Thanks in advance for any input.

i have always had the rain sensor option. not adjustable. it might be different on newer models

Not sure about the newer models, but my 2000 interval is determined by the speed of the vehicle.

cool. that means go faster!

Actually, in auto mode, it's not the vehicle speed but the rain drop density on the windshield that determines the speed of the wiper. I don't know how it works in manual mode since I never use manual mode. But I would think the speed is fixed in manual mode.

I do not have the rain-sensing wipers
 

Yeah, sorry...I don't have auto either.

Q was right the first time. In 2000, the ML320 did not have a rain sensor wiper available - at least from the factory. So, the faster you go, the faster the wiper cycles (interval setting). (Maybe late 2000's have them as it became standard in 2001.)
