Sorry, but that sounds like some BS to me. If that was the case then your heated seats wouldn't work.
Not necessarily since there are separate control circuits in one module. The wheel heater is commanded on and I can hear the relay click, but it turns of again immediately. So, the issue is somewhere in the feedback circuits that will turn the heater off. First wheel supposedly had an open heater. I don't think they measured the heater resistance this time assuming that a second bad heater is unlikely. My thought currently is that the module has an issue and leads to failure of the wheel heater (i.e. overtemp), since both wheels did work for some time.
If there is a short in the circuit, from a burned out heating element for example, the relay will cycle on and then off in 3 seconds or so when it detects the short. Could be the steering wheel, but why did the new one fail after one week? Could be the controller, but why did changing the steering wheel get it to work?
Can't wait to hear the outcome of this one. My money is on a defective controller.

Heated seat controller finally came in yesterday. Installed and still not working. Per Chrysler, steering column controller should be replaced next. Dealer found one and installed. Called to say all is working well. When I picked up the car, it was NOT working. I don't get how they can say that it tested functional when it clearly does not work.
So, back to square 1. I still think that one of the controllers was the culprit, but it damaged the heating element in the wheel in both wheels.
Checked the steering wheel and all seems OK. Best guess now is that there is a wiring issue somewhere. Dealer will pick up car on Jan 2 and drop off a loaner. At least they are trying to be customer friendly.
I had this happen to me during the winter of 2012... The dealership messed around for a while and first replaced the control module and then went on and looked at some other things and ended up replacing the steering wheel saying the heating element in the steering wheel was defective and had caused the issue... Either way, got a new steering wheel and control module. It seems as if they replaced both thus far?
My drivers heated seat just stopped working. It has similar symptoms to yours where the switch lights up for a couple seconds and the shuts off. The passenger side seat and heated steering wheels both work fine. Mine is a 12' Overland. Any ideas on this one?
