I have a Toyota Avalon 2001 in South Carolina.
When the dashboard multi-display reports a temperature >84oF, the clock and/or trip odometers reset, and other readings go blank.
When the car cools sufficiently, all functions resume (though clock time has to be reset).
The problem has been narrowed to the multidisplay module or its connectors.
Is there a way to keep the car interior cool when it sits unused in a parking lot?
I currently leave the windows open ~2in behind rain covers, installed last year, that prevent unpredictable thunderstorms from introducing mold through the partially openned windows.
I currently use a reflector in the window. Both of these observably drop the cabin temperature ~20oF ,
yet it is not enough.
I have tried a fan, powered by the car’s battery, but extrapolation from measurements indicates that before any
fan moves enough air to have significant effect, it will leave the battery too drained to start the car.
A solar panel powered fan generates more heat than it removes.
Is there a way to remove the expose (and reseat) the multidisplay connectors, by just removing the padding above the dashboard?
I have the service manual, but have not yet found how to get access to the multidisplay, without removing the seats, and all cowlings from the center console forward.
Thanks in advance for any suggestions,
