wiper motor replaced... same issue

[Fixup]

My wipers stopped working on my 2005 Cayenne S, and after reading some of the posts here I decided to get and install a new motor.

The same issue has come up again they simple do not move. I can hear the motor run, but nothing works at all. When I replaced it, I looked at all the linkages and bushings, but they seemed fine.

Is it possible it is an electrical issue? I haven't found any other posts on the site. Can anyone suggest something?

You can hear the motor but is it actually operating? I assume the wiper arm spindles are in good condition and the retaining nuts for the wiper arms tight.

The wipers actually work when it is not raining, however, when it rains, then just stop. I have also tried unplugging the sensor from the windshield. I plugged in my Durametric and it gave me the following error code

0 Module failed to initialize.

It says that there may be a wiring problem to my computer, however every other diagnostic report works.

So, the wipers work when it's not raining, which is not all that handy, as you can imagine.

When do the low beam headlights come on too? The rain sensor is tied to both wipers and low beams.

I don't understand. You say you can hear the motor but nothing moves then go on to say the wipers work so long as it's not raining. So.... if you turn on the wipers when it's raining do the wiper blades sweep across the windscreen?? The wipers will not operate if the front hood is open.

I know it sounds crazy, but yes, when it rains they do not work. I can hear the motor running, trying to get them to wipe, however they simply will not. Hood closed. Nice sunny day? No problem. They work just like they always have. I have no idea.

yes the low beams work when the wipers don't.

That would imply that the computer signal is there and correct and the problem is in the sensor.
