My rear passenger window makes a pop noise when I lower and raise it... its also strange.

 

i got the slow passenger windows too...and get the funky noises....smh

 

My passenger window always loses the race between the two, as well.

 

this is why

hope they dont need replacing bf u got this thread, as if u get it early u can 'lube' it, theres all the info u need. long thread, lots of info.

 

somtimes it can b grit in the track or some debris, which is scrapin the window, look for scoring marks on the glass.

 

My weatherstripping on the two front windows was declared effed up by the dealership, and slowed down the passenger window, as well as misaligning it.

Repaired finally under warranty - both windows move the same now.

 

i have had the exact same "tapping" noise coming from the rear sound just like someones tapping on the trucnk lol. any one else heard this? it only does it at a stop and its 3 taps everytime it happens

 

i have the same ratlle it sounds like a bolt or something is loose in the dash somewhere...gonna takle that next spring...rip the dash out and see what i can see lol

 

had a random screw fall from under the dash somewhere and hit my leg while I was driving today. lmao. I'm not going to worry about it unless something starts rattling. Lol. I'm not driving a Mercedes am I?

 

rattles just annoying and i want it to go away already lol
