Windshield wipers revisited

[NelsonMX]

Hi all,

I know the wipers have been covered quite a bit but I seem to have a slightly different issue causing a similar problem.....

In my case the drivers wiper leaves an un-wiped streak in the center of the blade on the upstroke. The passengers blade leaves an un- wiped area in the lower area regardless of blade direction.

Here is what I found: On the passenger wiper arm there are two 16mm nuts holding the arm on. The right one is loose. When I torque this nut down both the drivers and passengers blades work perfectly! No elephant sounds either by the way........ The problem is the nut loosens as soon as I use the wipers and we are back to square one......

Just wondering if anyone has seen this on their Cayenne, and did replacing the two nuts and washers resolve the issue??

PS I have tried blue loctite with no success......

Chances are the wiper arm has been worn by the splines on the spindle caused from use while the nut was loose. Inspect them carefully for damage but you probably have to replace the arms. How old are the wiper blades and do they move easily on their pivots pins?

The bolts and spindles aren't worn, the wiper blades are new, and the pivot points are free.

The only issue is the right nut loosens. I think I will order two new nuts and the two washers

and see if it cures the problem....I was just wondering if anyone else had this issue

as it causes the wipers to streak and miss areas....

What loctite are you using? I have used 242 which is blue in colour and for low torque situations.
