The Brondell seat is dripping water from underneath near what looks like a drain plug on the underside. Can this plug be safely removed and what is its purpose. Thanks.

Odds are you have a plugged drain tube somewhere.
The sunroof will have a drain tube running down one side of the car through one of the pillars.
The HVAC unit has a drain tube ... but that usually drains on the passenger side ... so probably not that
The windshield cowl area (where wipers are) has a drain tube...which if plugged could lead to water getting probably on either side. You may have to experiment with pouring water in those areas and seeing if it freely drains to the underside of the the car to determine which drain tube could be the culprit.
Ohter non drain tube issues ... you have probably already checked ... like the rubber seals around the driver's door
Helpful?
Good luck on your troubleshooting

the FSM may cover this.
btw, my new jeep has this tube in a funny spot.
unlike any car if owned or restored (many in 50 years.)
the tube on my wrangler is near center of car, oddly
it must drip water or it IS CLOGGED. you are correct.
the water in the air must condense out and drip the the drain pan. then out. if it gets works the passengers feet and floor mats will soak in
condensate (pure water)
best way is to get under car (safely with real jack stands, never use a jack or bricks ever) and look. for the tube. its not easy but its there.
mine is very hard to see, in fact , it dripped in my face before i found it.

my 08 fsm
shows the Evap box rear has drain pipe and foamseal.
lower left bottom corner in photo.
prevention., there is a spray to buy that can kill fungus growth.
pull filters and spray down there.

sorry i dont have real fsm , for 2010
but mine does NOT show the tube path at all.
only the source of the tube.....
good luck.!!

you must go to HOME DEPOT, and get the part, and fix it.

God bless you

Jack up the front of your car safely and climb under.
Remove the under tray fastened by 8 bolts

then use a 17mm wrench to remove the drain plug

Is what the liquid plain water or coolant (water mixed with antifreeze). touch and smell the liquid, no smell = water, antifreeze smell and oily feel = coolant.
If plain water, could be Air Condition condensation dripping from condensation drain which is normal. (this drain is usually located near the center of the vehicle).
If coolant, could be leak(s) from: radiator, radiator hose, heater hose, water pump, engine freeze plug. A coolant system pressure test should show what is leaking.

Hi There,

Just call Brondell toll free at 888-542-3355 and they we can trouble shoot the problem. If it's in warranty, repairs may be covered and outside of warranty, discounted servicing is available.

Hi, The defrost drain behind the rear freezer panel is plugged. Remove the rear panel and clear the ice away from the drain. Then you will need to flush the drain hole with hot water to make sure it is open.
Some models require an after market drain heat kit.
Please get me your model # and I can look this up to let you know if you need that heat kit.

Thanks
Vic

Hi, There is a drain plugged. Look on the back of the freezer. If you can not see a drain hose, look underneath. Blow through the drain hose and clear it. If you can remove a panel near the fan motors and get to the drain there, you can clear/flush the drain out too.
I hope this helps you.

there is a drip pan located underneath you ref but most likely your prob is a plugged drain line coming from the freezer. when you ref goes into automatic def the water doesnt run out into the drip pan but instead onto your floor..

you can clean the drain line by removing the rear cover in the freezer compartment and using hot water to thaw the drain below the evap coil.
