No cooling from rear vents - 2000 Sienna LE
There is no air coming out of ceiling vents at all, but air flows nicely out of the vent under the front passenger seat. Searching the forum, there have been descriptions of problems that have no rear air at all, but it's not clear to me if the vent under the seat is part of that rear system or not. One thread indicated a failing fan motor, but if that were the case, wouldn't the under-seat vent not blow too? I really don't know where to start here..... thanks!
