There is a water vapor coming from the vents in our 98' monte. I happens all the time, if the fan is on it's coming out of the vents. Also when I put my foot on the brake to slow down or if I turn I can hear something hitting the fan, almost like water is hitting the fan. Today we drove the car around town and I actually noticed it dripping on the carpet so I just shut it off and rolled the window down. I was thinking that maybe it was a heater core but I don't think it is cause the water doesn't smell like antifreeze...

my girlfriend is freakin out cause she doesn't have a/c lol any help?

 

Have you gone under the car and unplugged the condensation drain?
On the passenger side firewall you should see a tube come out, go to a 90 degree elbow and have a tube run down to the bottom of the car. Blow some compressed air in it or pull off the 90 degree bend and clean out the bend/tube. I bet a bunch of water flows out.

 

thanks, I'll check that out tonight when she gets off work

 

Did that help your issue englundjd?
