Sorry for the rant, it's the wife's car and I'm just tired of this already...
I too was a technician for a while before changing career paths. This will help understand my frustration:I'm not defending your dealership, but I did work in the automotive industry with Ford for a few years and have a working knowledge of how quality issues are resolved.
A TSB is issued when the root cause and corrective action for a specific issue is resolved. It is possible that for the TSB related to heated seats, the root cause was found to be an error with the "module" that was referenced by the technician, and the corrective action is to replace that "module". If the tech tested the module and found it to be operating correctly, then the TSB is not applicable to your vehicle. There can be similar issues that are totally unrelated to an existing TSB.
You stated that the seats do not get very warm on the heat setting and that they do not get very cool on the cool setting. The question is: is the operation correct but not meeting your expectation, or is the operation incorrect? If you got a call stating that they were able to replicate the problem, it sounds like the latter. Now the techs need to identify the root cause and compete corrective action, which may lead to a completely new TSB.
Curious did all this happen at a stand alone Lincoln Dealer or a Ford/Lincoln dealer?After 37 days, I finally got the car back. Seat TSB was performed and since the tech ripped the leather (zipper), I have new leather also. All happy and relieved... Only for the A/C to turn off on me 4 times on the way home. GRRRR
