iam hoping if someone here who has fixed there water leaks on their bonneville can help me out. this is really frustrating, well i thought i fixed my water leak in my 95 bonneville, well it rained today and i still get water a puddle in the passenger front and the passenger rear, but the driver front and rear is dry. i just dont know where this water is coming from. i sat in the car while it was raining and trying to observe where this water is coming from and i dont see any leaks at all, i looked at the weather stripping and i lifted the lip of it and its dry, also its dry all around the weather stripping, before it rained i put weather stripping aheasvie all around the weather stripping and i also put some rope caulking on the top rain guards and still i get water in the pass front and rear. any ideas where this water may be coming from? all of my undermat is all ruined from the water and its a mess, i just want to find this dam leak, i have no sunroof, to me it seems all the water is in the middle, but the pass rear on the side by the weather stripping is all dry, i just dont' t get it, for all you you guys and gals who found your water leaks in your bonneville where were your leaks at?


1995 bonneville se

Its the door seal thingy or something

No water on the door seals? Pull your A-pillar trim off the next time it gets wet, and see if it'* wet inside. If not, I'd bet your evap core is clogged, and the box can't drain. It'll overflow on the inside of the car in that situation

the door seals are dry in the inside, next time ill pull the a pillar trim off and see of water is present also where is the evap core located on this car? if it was the evap core wouldn't my driver side and driver rear also be wet with water? the driver side and driver rear is dry only the passenger side gets flooded with water

The Evap core is on the passenger side, and will leak there first.

is the evap core in the inside of the passenger side? or the outside?

so then do i need to replace the evap core? or can i just drain it and reuse it? also exactly where is it located

That seems to be very popular place to leak in alot of Pontiacs in general. My '98 GAGT leaked in the passanger side pillar too. But fortunatly, not in the Bonne.......Good luck with that.

mine leaks in the right rear...carpet is shrunk so its leaked for awhile////seems like door weatherstrips....

It'* both inside and outside the car. Read the Techinfo article on the subject. Cleaning should be sufficient. ASSUMING that'* your problem.
