THe title is pretty self explanatory. My ac will only blow if the know is on the highest setting. Also my drivers side floorboards are allways wet. I live in GA and it is summer right now and i will leave my window open all day to try and let it dry out but it still stays wet. Any advice would be greatly appreciated.

My truck is a 2001 dakota 4.7 V8 4x4

 

1. blower motor resistor (may need to replace the pigtail if melted, and it probably is)

2. Heater core may be cracked/leaking. Is it warm water (engine coolant) or cool water (condensate)?

 

As long as you have high say thanks for that.

The wet floor could be two things easy to check well should be

First check to see if its coolant green in color unless you use only water that is it should smell like coolant also.

Second is its probably a leak from the drip line look to see inside your engine bay if your drip tube has an elbow facing down if no drip elbow that's the problem a missing elbow. What happens is as the water drips out if no elbow it will tend to get sucked back into the cab you need the rubber elbow.

Do a forum search on this lots of posts on this problem many have Pic's with them on the elbow fix/fix's

If coolant well you know what comes next

Fan problem could be the resistor pack easy check
