...well, after reading some of your comments, I decided not to go to the dealership and do this myself. This may seem "ghetto" fix for you guys , but let me tell you my Z is now "rattle free" and it feels as the day I drove off the dealership when new.
I had a cheap floor mat left over for my Altima (picture below) bought at Autozone. I used a knife to cut 3 pieces, about 6 inches long and 3 in. wide. I did fold them and placed them in beetween windshield and dashboard (pics below).......let me tell you....it works!!

 

I will take the rattles not to have my dash look ghettofied like that. Just my .02

 

Oh good god, I'm mortified.... please keep that one to yourself, and park in a garage...

 

wedging something bewteen the dash and windshield is how I got rid of mine too.

 

Damn that looks ghetto like those delivery vans with crap all over the dash. Surely you could do the same thing with a little more subtlety?

 

there has to be a different way to do this... i did something similiar, but no where near as noticable..

 

I thought you were going to take the dash apart and pad under the dash with the floor mat. That would work too I bet (it'd be more work) but it would probably look better.

 

hahahahaha at least it worked for you

 

I agree - the old mat wedged in there looks a bit unfinished. Maybe with a stink tree on the mirror........

I've "cured" many of these noises with a little Velcro (the "soft" side). If you're careful when trimming and placing it, it can look great. I've used it as weatherstripping on alloy bodies (e.g. my '58 Lotus 7) and to support plastic panels (e.g. pillar trim and dash on Mini Cooper S).

Get the "industrial" stuff at Home Depot etc. It sticks well and holds up for years.

 

Just leave the mat on your hood, makes for a good hood ornament!

 

Well I did the same thing EXCEPT I used rubber vacuum hose and did the entire length of the dash . . . You cant tell there is anything there and it looks factory.

I cannot live with the rattles. Nothing pisses me off more than rattles. You should have seen me on a recent 500 mile trip. While the girlfriend was driving I crawled all around the cabin searching for the sources of my rattles. I fixed 2. One required the removing of the temp sensor in the top of the passenger side dash. Its that little round plug looking thing. It has always given me problems. POS.

 

+1

 

I hear more rattles in the rear than in front if any. So I will reject this mod. lol. but if I were to approach it I'd use cut it more cleanly and insert it so it would be cleaner. nasty to look at that everyday.

 

I used an old pizza box

 

I use chewing gum. After I'm done with it I just stick between the windshield and the dashboard. I'm almost halfway across!!

 

lmao! ... i hope that was a joke

 

and why not go and get a strip of door weather stripping (rubber or foam) ?

 

Ghetto fab

 

I used my wifes used maxi pads, it works great and it matches my red calipers....

 

dude, that was gross.
