My Mustang has started to leak water on the drivers side floor whenever it rains. I tried looking up where to find the front cowl drains on a 2015 Mustang but I have had no luck searching online. I can only find information on models 2014 and below. Does anyone know where the cowl drains are on a 2015 mustang ecoboost premium or heard of any other reason water would be leaking on the drivers side of this particular model?

 

2015 was when the platform changed, which is why it's not the same as '05-'14.

Still, they ARE there... Can't find anything on it...

If you take the passenger side cowl cover off, you should be able to look
in and see it.

 

check this!! could be the same!!

some have been known to have pin-hole sized holes in the seal of the roof seam that leaks along the a-pillar then into the dash & the floor
2014 do the same

 

Yes, that is a totally different problem, and is documented.

 

oof.
that sux

 

 

 

(Sorry, that pic wasn't my car,
it was just info I found online...)
I have a 2006, which doesn't have this problem;
only the 2015+ seems to

 

there are 3 stickers when you open the drivers door,on the frame
before they paint
check that they aren't loose
