08 Town n country , i was able to retract the rear drivers side piston using the dice, but the passenger side turns using the dice but the piston wont retract

SOURCE: how do i compress the caliper piston on rear

you should have to turn in the caliper piston there is a special tool for this looks like a cube and has different notches on it for different cars,you can get it at like autozone for cheap $5 or less,,but you attach it to the extension and then a ratchet and turn the caliper in,,,,you ccan try to use a needle nose pliers to turn it in but thats not always easy,,turn it clockwise til it stops,,it will almost be flush with the housing

SOURCE: the passenger side floorboard gets wet =

is it only when the ac is on? there is a pan under the ac unit that has a hole in it to allow the condensation to empty. if that hole gets plugged it could cause the condensation to build up and back into the inside of that car. i unplugged mine and floor stayed dry

SOURCE: why does my 2002 town and country blows cold air

These vans have a bad design on the heater blend door which is located on the heater box behind the dashboard. The hinge on the blend door breaks and will not move causing the air not to circulate through the heater. Do you hear any clicking noise? You may get lucky with a repair. Go to the eBay site and in search put in-blend door repair-
Good luck and thanks for your question and I hope my suggestions help. Don't forget to rate me.
