I had the same exact problem on my 2000 LeSabre. Lots of clicking
going on under
the seat when pushing the heater button, but the
indicator light would stay on

way to reset it off.
It was out of GM
warranty but still under an extended warranty. They
replaced the heater element
in the seat which solved the problem. I
think it was about a $1000.00 job.
