Default Ford TSB: 09-4-8 INOPERATIVE HEATED SEAT(S)

So the wife's 2008 Ford Taurus X driver's side front heated seat went inoperable a few weeks ago. I originally was just going to leave it alone until late summer/fall - but discovered the following TSB as well as numerous complaints/posts/how-to-fix-it's on various discussion forums.

The car only has 44,000 miles on it. It is again the wife's. Priority level on this is low currently, but as cold weather returns it will ramp up exponentially.

That being said, armed with this TSB, what are my chances of having it fixed at no/low-cost to me seeing as it is out of warranty?

This DIY post does not look enjoyable at all: http://www.myfordfreestyle.com/forum...=heated%20seat

INOPERATIVE HEATED SEAT(S) - BUILT
BEFORE 12/14/2007

FORD:
2005-2007 Five Hundred, Freestyle
2008 Taurus X, Taurus

MERCURY:
2005-2007 Montego
2008 Sable

ISSUE
Some 2005-2007 Freestyle, Five Hundred, Montego and 2008 Taurus, Sable and Taurus X vehicles built before 12/14/2007 may exhibit an inoperative heated seat(s). This concern may be caused by an intermittent open element in the heated seat mat.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE
The heated seat system is controlled by the heated seat module located underneath the front passenger seat cushion. The heated seat switches are part of the heating ventilation air conditioning (HVAC) module but the heated seat system operates independently from the climate control system. The heated seat module regulates seat temperature by monitoring resistance of a thermistor type thermostat located in the cushion heater mat. The heated seat module is designed to remain on, heating the seat and maintaining temperature until switched off. For vehicles built before 5/1/2006, the module will time-out and switch off after 10 minutes.

1. Refer to Workshop Manual (WSM), Section 501-10 for pin point test on inoperative heated seat(s).
a. When testing the heater mats resistance and circuits for an intermittent open, technicians should sit in the seat while testing the circuit resistance, move the seat in multiple seating positions and apply pressure to several areas of the heated seat mat to ensure the mat element is not open intermittently.

2. Refer to WSM 501-10 for heated seat element replacement when an open electrical circuit has been identified.

There not to bad to do. Just take your time and remove the seat from the car. look for a burn spot in the element. Instead of hog rings use zip ties cut them and turn them into the cushion. Remove the old element from the seat by pulling slow to make sure chucks don't come off. I seem to do one a week in the winter at the dealer I work at. Takes me about 1-2 hours depending on model I would plan for longer.
