water on passenger side floor

water on passenger side floor

the door seal is fine and the door is dry inside and out

i think its coming from the cabin filter

my brother had the same problem in his 99' Grand Prix GTP

any one else had the same problem?

Yes, my seal around the firewall was old, worn out. They had to reseal both sides. Both floors would fill up with water about an inch every time it rained.

it did it to me too,passenger side only
sounds weird but if you have that plastic cover where your wipers are...take it all off and then clean it out,no leaves or anything,then make sure when you put it back its all sealed up tight.....

it worked wit me

do you have an aftermarket car alarm/starter?? I had that problem in my z26. the hole in the fire wall was in the drivers side but it would fill up the floor on the passenger side. Just a thought

me I had the air box under the wiper arms... its gasket was shot and inspect the firewall for where wires go through. Also where the main ECM wiring goes through the firewall I had a leak there too

Smell sickly sweet? Where is the heater core?
