The tray below the evaporator has a drain tray with a drain hole to fit in a hose. Due to high level off dirt accumulation it is possible that the tray drain is clogged and prevent the condensed water to flow out. Open the unit and look under the panel to find this, use a thin flexible cord to push into this drain hole to clear it. You can also use a good air jet with the flexible nozzle pointed to the hole to push out the dirt.

Looking to unclog the a/c drain hose/tube; no water anywhere in the car but when making turns sounds like possible water sloshing around.

Look around the firewall for flaps or holes that are blocked at the bottom.

Rain water or wash water accumulates in the body and sloshes around.

Debris can block the drainage holes, just like in a gutter.

Good luck to you on this one.

How can I unclug my sunroof?

The best item is weedeater (weedwhacker or whatever you call it) nylon. It is thick enough to push blockage out and flexible to handle any bends. Also check the exit of the drain tube (behind a cover near the front wheel on my GTV6) as an accumulation of mud will prevent the gutter from draining out.

The drains on my sunroof leak when it rains and water comes inside the vehicle. How do I unclog the drains?

A big leak with that model is the drain tray in the rear under glass has broken loose. To check the drains, park vehicle on an down grade, open the glass and pour a cup of water in on each side and the water should come out the front, Turn the vehicle around to check the rear the same way.

Dou Therm Brisk Air not running

Turn the ac off go up top the coach and remove the cover. Look for fan blockage, Wasp, mud dauber etc. Caution if it is wasps they will chase you off the end of your coach. Take some spray with you. If there is no blockage the fan motor is toast.

The thermostat needs to be reset. Turn it off and hold the top and bottom buttons in at the same time and turn the thermostat on. In a few seconds will read FF and you should be good to go.
