Any of the following can cause this...........
1. Clogged drain tube on the passengers side.
2. Disconnected drain tube on the passengers side.
3. Cracked a/c housing.........
because of condensation
your drain line for your ac evaporator core is plugged up. A service station can blow this out for you.
Heater core leak, or stopped up condenser drain line.
there is a leak in the drain pan that the evaporator sits in inside your furnance
all ac systems drip water if working correctly-----if water is getting on floor of car,the drain tube is plugged
You cant
normally if a car is leaking water it is because of the air conditioning in the car being cold so the car will sometimes leak if the ac is running long enough and cold enough.
can you block the high side on the ac on a car to stop a leak
Look for the tube that takes the condensed water out of the cabin these sometimes get knocked loose by the feet of the passenger's
had new blower motor installed in my 2006 gmc now waater is leaking inside car when ac is on
The condensate drain is most likely stopped up.
If it is WATER - The AC drain plug may be fouled and needs clearing (small rubber elbow on the firewall), or you have a windshield leak when it rains. Usually the AC will leak on the passenger side. Door seal leaks will also cause this. Climb inside the car at home and have a friend run a water hose around all the seals. See if you can locate the leak. If it is COOLANT - you have a leaking heater core or feed tube hose.
