Water leaking no A/C

welcome!

condensation from a/c always leaves a puddle under the car.

 

Don't use the airflow and see if there's still a puddle

 

Sounds like moisture condensation from using the AC, all cars do this. I freaked out too when my friends truck did that also thinking were gonna be stranded.

Just like when you spray air out of compressed air dust can and hold the nozzle for a while. Moisture and or frost like stuff will form on surface side of dust can.

 

gotcha, i was confused by the o/p. maybe it's excess. see if it continues.

 

If the light next to the "A/C" is on, then the AC is on. It doesn't matter what airflow speed or direction is set at. That puddle would be the condensation from the AC. There shouldn't be a puddle if the light next to the "A/C" is off.

 

Although if you have your control set to windshield defog/defrost, and turn on the fan, the AC compressor will cycle to dry the blown air . . .

 

I would recommend locating the exact source. If it turns out to be under the evaporator box drain, maybe the drain is plugged and taking several days to empty. How is the humidity up there in WA? I know it has been a dry summer for most of the area. The higher your outside humidity, the more condensation will accumulate in the E-box when you have the A/C set to outside air. Any odors?

 

Good call, that's got to be it.

 

I don't think it is possible to shut off the air flow completely.
I also don't think that it is possible to completely shut off the A/C as it also dehumidifies and helps with keeping condensation off the inside of the windows.
Safety considerations.
