I have a '01 grand caravan and when taking a long trip the condensation from
the air conditioner runs under the carpet on the passenger side and collects
in the carpet. I have had it to the dealer 2 times the second they said the
cabin air filter was plugged, it didn't help one bit. Also there is no
water dripping under the car other than from the door jam on the passenger
Rick, the drain is stopped up, you need to try to blow it out or rinse it
out by putting water thru the front cowl, if you park under a tree that
drops alot of leaves I would recommend moving the car from it.
Plugged drain tube. Jack up the front and look for a rubber tube with a
slit in the end almost directly under the heater core. The end of it
will look like it is solid, it actually has a slit that is supposed to
keep the dirt/bugs out while letting the water out. They get crud in
them and plug up. Take a 6-10 inch piece of wire (coat hanger works
great) and clean out the dirt. DO NOT STAY UNDER IT WHEN YOU CLEAR IT
OUT. To make sure it stays open flush the tube with water and clean it
once a year. Also to help you from having the normal smelly A/C from
bacteria remember to switch to heat for a couple minutes before shutting
the vehicle off after using the A/C for a long period. That smell will
really make you sick if it does start growing.
