I have exactly the same problem, except I know what caused it!
I forgot to close the windows last night, and there was a big storm.
This morning the seats were soaked. My Camry started up fine, but I have the exact same symptoms, no rear defrost, no a/c, no front defrost, no ac/heat temp control, and no recirculating flap control. The fan blower is working fine. Everything else seems to be working well.
Same as you, I checked all the fuses, but they are all good. Perhaps the rain has shorted something out in the dashboard on the drivers side. I'm hoping that a few days in the sun drying out will make it all better, but I'm not counting on it.
Anyone else who might know how to fix this problem?
