What inspired them to say it needed replacement, any tests/checks. Unfortunately dealers tend to be parts changers when things go wrong, so expected answer really. Sorry I am no help, but someone more knowledgeable should be along shortly.

Bad! I had a problem with my system years ago when my 80 was only 4 years old. Recirc button would not work. I decided to buy a new ecu but this burned out. I took it back and they replaced under warranty. Then 2nd one burned out so I decided to take to toyota who renewed the control panel and ecu. Again ecu burned out after a day. Took it back and they found a fault with recirc motor which they replaced together with ecu number 4. After that everything was and still is OK. I guess with the WSM and a PhD in witchcraft you might be able to trace the fault but I know toyota had to fix my problem by referring to their world library to look for answers to similar type faults other customers had had.
Look at the rear of your control panel, you may see a switch which may be covered with tape? Lift the tape and slide the switch to the alternative setting, it changes the circuitry inside to suit different models.....of course at your own risk but I have been down that road.
EDIT: Check the control cable is free along with the heater valve by disconnecting them both, the servo that drives the motor can stick.
