I have a signifigant amount of water dripping from under the vehicle. My ac is not on. My front window will also fog up at times. Does anyone have any suggestions?
With the hood open so you can obseve, you will find the a/c compressor cycles even though you have not activated/ with button.
I have found the compressor cycling in most of the air distribution positions.
This is not endemec to just Jeep, most late models do this.
You will even find it cycling when in the floor heat only position.
That being said, you are likely seeing condensate.
If I'm right, the fogging you experience usually occurs immediatly at restart and clears in less than 30 seconds.
If thats the case, you are seeing the damp air that is in the heaterbox that was a result of the cold evap core causing condensation getting blown out of the vents and recondensing on the glass.
Then within 30 seconds the compressor engages and de-humidified air is blown from the vents.
And with that, the glass defogs almost instantly.
Anyways, most manufacturers are using the compressor in most air positions to act as a dehumidifier now days.
I know that one of the few positions it doesn't is the dot between the floor air and the dash air. I usually keep mine in this position to prevent compressor drag and corresponding fuel economy loss in the cooler times of the year (now). I close all the dash vents to stop upper air flow during this time of year as well.
Hope that was helpful,
