Seat heater not turning off.

Just bought a 2020 White Nightshade Limited from a out of state Toyota dealership. Noticed after we bought it we could not turn off the passenger seat heater. Took it to a local dearship and they found a can of pop had at sometime exploded under the seat and coated the area, including wiring and connections, under the seat with sticky syrup. Certified warrenty will not cover as the say it is an outside influence as the cause. Waiting for original dealership to make it right. In the meantime we have a trip in the next few week with summer temps. Is there an easy way to turn it off. Pull fuse? Im having trouble identified which one. And not sure which plug to unplug under the seat. Advice please?

 

The second dealership couldn't be nice enough and unplug it for you?

Think its #13 under the drivers dash.

 

I spilled water on my switch and it got stock on full blast so I had to take it out and dry it. Dumb place to put the switch.

 

Yep, soda and cars do not mix.
