Wiper speed info

[mkovic]

My car seems to have a problem with the speed input to the wiper motor. I only have 2 intermittent setings and one super fast. Reading the forum I realized that the problem is probably with the speed signal to the wiper system. The speedometer works though. Since my OBC doesn't work as it should either I was wondering if the problems are related. Where should I start to look?

Thanks,
M.

ok most cars would be like this.
One push down gives a single wipe
one push up = intermittent
second position up = slow
third position up = fast
intermittent is adjustable
whatever position you are in when you come to a stop the wipers will go about half the speed they were going

Sorry, I was not very clear with my first question.
The problem that I'm having is with the slow continues wiper setting that should switch to intermittent when the car speed drops.
In my case this setting results in intermittent wipes, just like the "normal" intermittent setting, regardless of car speed. So instead to switching to continues wipe as the speed of the car gets higher, it remains intermittent.
I assume the wiper system must know the speed the car is traveling at and was wondering from where does the system gets the input on car speed? Does the wiper system uses the same speed sensor as the speedometer? Since the speedometer works just fine I’m trying to figure out what went wrong with my wipers and OBC.

you can set the intermittant setting, read about it in your manual, its really cool!

I've never mastered it. It seems to do whatever it wants regardless.

jay try this
from off switch to intermittent and immediately switch back to off,then switch back to intermittent when you want a wipe....you have just set the delay....

Are you saying that SLOW is alwyas intermittent?Or is all right until you slow,then never goes back to slow from intermittent

[mkovic]

It's always intermittent.

specify what the OBC problem is). Do you have Radio volume afected by car speed? What about Cruise Control?

The OBC won't give any data on avarege speed or fuel consumption. It just shows either blank lines or some unrealistic values such as 99.9 l/100km. I have an aftermarket radio installed so the volume is not affected by this. No cruise control in my car, though (unfortunatly).
