Thread: AC Drain

Were some of you saying yours drips inside the vehicle? That doesn't sound right. Mine stays outside

Colin,
sounds like the evap coil in the cab is freezing up. Once the ice builds up the air doesn't flow thru the coils so the cooling will drop off, also the ice will often block any remaining water in the system, hence the sloshing sound .
If you park it up and there is still water dripping 1/2 hour after you stop then definitely ice-ing up of the evap coils.
The most common common cause of this is there should be a temp switch on the evap coil that stops the compressor is it gets below 2 degrees ( It could be 4 or 6 degrees) . I've had them come off the coil and hanging in the breeze. It could just be it's just soooo humid at the moment.
A short term solution is to stop the aircon for 10 minutes with the fan on high, once the ice melts you'll get another 1/2 hour or so out of the aircon.

Cheers Glen.
