2020 with grease streak on passenger side window

4 month old Taco with a grease streak on passenger side window.

Just comes back after its cleaned off. Clearly something inside the door is applying the grease streak.

Hesitant to take it in to the dealer for repair... not interested in some service technician disassembling door and installing squeaks and rattles.

Anybody else have this problem? Solutions, especially ones avoiding door disassembly.

 

Friday was yesterday?... Hit it with some compound. Then glass cleaner. If that doesn’t work, maybe some 0000 steel wool and then compound and then glass cleaner.

 

OP are your windows tinted? If so, don't do this. Pull your door panel, it's super easy.

 

You’re right. I didn’t realize it was inside. Definitely coming from inside the door panel.

 

Yup just pull the panel and take a look yourself.

 

First taco owned since this march, never saw anything like it on any vehicle.

 

I had a little grease residue (would remove and come back) on my '18 D/S window exact same area as yours when was new. It eventually corrected itself.
I believe some just get a little too much lubricant on the mechanism when assembled. No big deal.

 

Pop the panel clean it off the grease wherever it is then hit window with some Chemical Brothers with the duel microfiber cloths will look perfect.

 

Totaled

 

Does your truck get wet alot? Frequent washing? Has your truck gotten wet recently? Windows down in the rain?

I usually sed this on vehicles that have recently been washed, or see a good bit of rain with the windows down?

 

Clearly at work here. Take it apart yourself and drive those demons out!

 

Sandpaper or a grinding wheel too.

 

Someone at the dealership puked in it, and out of it.

 

Damn. I barely have 10000KM on my 2018 and those side windows are already Scratched to shit from the trucks own weatherstripping when rolling down. Very odd since I rarely roll em down and take very good care of my truck... I’ll ask the dealer About it one day but they will just say I did it somehow.

 

We are on a Toyota truck forum right? Not a Tesla or luxury brand forum correct? Hard to tell these days.

 

I know right!?

 

D*mn it do you have grease on your Lexus window? unacceptable!

 

Had this, too. Cleaned it off haven't seen it since.
