Funny...had the exact same thing happen about a month ago with the same symptoms and the "clicking."

I have not looked to fix it yet but it is probably either the element or the heater module. The "clicking" leads me to start with the module (about $100 new).

Apparently the module from the passenger side can be swapped to confirm. I think the module is on the underside of the seat. The service manual notes removing seat, but I am going to try getting at it without removing (though it is not that hard to remove).

There is also a module that can be accessed fairly easily from the front with the seat up all the way (and plastic front cover removed by lifting up to release clips and pulling forward). But...I think this is the memory module.
