Rear window wiper
Anyone else have issues with their rear window wiper doing a terrible job?
I live in Canada and dealing with the snow melt and grime/dirt for sand spreader etc. Leaves my rear window perpetually dirty. When I spray it with cleaner and turn on the wiper, it does a pretty poor job of taking any of the dirt away.
Has anyone replaced the rear wiper with something other than a factory blade and get a great experience with it?

The rear wiper on our Macan GTS always chatters on the first wipe, but is smooth going back. Other than that it does a decent job clearing the rear window, although the rear window easily gets dirty very quickly

I think the biggest issue is the pressure it puts on the window the further away from the pivot point it gets. Close to the pivot of the mechanism, it cleans ok.. the father out it gets, the worse it cleans.

Mine is a chattery mess as well. (2100 Miles on 2017 GTS) I just recently polished and put a glass coating on it and it didn't make a difference. Really disappointing.

Same here. The clockwise stroke is chattery and skips over most of the glass. The return stroke is smooth and does a decent job clearing the window. I doubt there's much to do about it, but it's on my list of things to get checked in another month or two.

when I took delivery of my CPO MT, the rear window wiper was pretty streaky.
I replaced the blade and it has worked great ever since! I try to use it sparingly - not leave it in
auto mode. I use it to clean the rear window glass and on/off manually, when it's raining.
I would recommend replacing your rear window blade.

For both your windshield and rear window, I recommend using a clay bar specifically formulated for glass and then treat the glass with AQUAPEL. Gently clean wiper blades with isopropyl alcohol every once in awhile.

Bummer! I wonder if different blade manufacturers would improve operation. TRICO lists a 15I as a direct fit replacement but a post on the other forum says it doesn't fit. Anyone tried it?

Whenever a wiper blade chatters, I always think that it’s old and the rubber has hardened to some extent. Replacing the blade usually helps with the chatter. I replace blades once per year, typically before winter hits.

I coated my windshield with Rain-X,. Bad move, now the wipers chatter. I'm going to leave the rear one alone as it is still functioning properly.

Yup....
My 2017 GTS rear window chatters like nothing else.
Once weather warms, I plan to clean, clay and treat the window in ADDITION to replace the one year old rear wiper.

Usually wiper blade chatter is due to the angle of the wiping blade relative to the wiping surface. The wiping edge needs to trail the blade, not lead it. Slightly tweaking the arm to achieve the proper angle should eliminate the chatter. The blade needs to be oriented so on the forward stroke the arm is leading the wiping edge, then at the end of the arm travel when it goes in the other direction, it kind of flops over and reestablishes that same relationship. If the blade is chattering on the forward stroke, the wiping edge is probably leading the blade in that direction, so it hops.
