Water collecting in drivers door of 2008 dodge grand caravan, in lower front corner of door is tape over a drain, I pulled the tape back and about 1/2 gallon poured out. is this normal? I assume that since I loosened the tape, that the problem won't occur again.

Question edited to add maker.
Question moved to model category.

The problem here is the wiring harness where it travels from the door into the door frame. Constant opening and closing of the driver's door bends the wires back and forth until they work harden and snap. This issue ONLY happens on the driver door.

Once you get inside there, you can check with a multimeter and replace that wire.

Dodge Grand Caravan No Power Window No Power Locks CAN Trouble

contact on the sensor for the door could be bad or you need a new sensor

pull on the middle of the rubber blade and pull it to the front of the blade holder and the back will come out then pull it the other way and the front will come out. then replace the new blade the opposite way.

The rear ac evaporator box is not draining very well,and it is blowing the condensation up threw the vents,most likely.The drain should be under the rear passengers side wheel well.

We have a 2008(same body) with the same issue. Just got back from the Dodge dealer and they said "they're all like like that" #@!& Not a good answer as we live in Syracuse NY home of 150inches of snow/season! Last year the right side wiper blade broke off because it kept getting hooked on the ice in that corner of the windshield. Chrysler should offer a fix of some kind because it effects the visibility of the entire windshield and is dangerous!!! The dealer said the other vents (set of 3 squarish ones) are actually for speakers on some models but they are in a lower/better position to heat the bottom of the windsheild and look like they should be able to have warm air run through them.
I think I'm going to double face tape a small strip of black plastic above the current vents to deflect some of the warm air to the lower edge of the windshield.
If anyone else has a better fix please post.
thanks,
Freexing in Syracuse!

usually left lower corner. sometimes there isnt one and the lower hose will need to be removed,

Drivers side at the bottom......may face to the rear or to the side of the rad.

There is a bundle of wires that are located at the back of the lower door track. We had the same problem and thought it was the door motor... actually one of the wires was just slightly cracked through and needed to be stripped put back together and taped with electrical tape....look at this closesly

what motor...3.0 liter has a pump driven by the timing belt....3.3 is on the passenger side front lower corner of the timing cover
