The car is twelve years old and I find after a few years if these things are not used regularly they seize up. It pays to use them once a month just to keep from seizing up. The same with my emergency brake. I had to replace the cables because I never used them. To sell a car all that stuff has to work to pass a safety. Not sure about seat adjustments.
This seems to be a more common problem, occurring primarily because some lazy guy with an air drill does not properly "start" the lug nut by hand before he puts the air wrench on it and cross threads it.
We just replaced a couple and it is interesting because depending on the car, some have a place on the back where you can spin it and it will allow the broken lug nut to be pounded out of and a new one put in its place. (Be sure you attach washers and a nut and tighten down the new lug to pull in the back nice and snug before you consider the job done.

The radiator fan relay is located behind the grill on the driver's side of the vehicle. There is no relay in the distribution box. There is a 40 amp fusible link, however, in that box. The relay (behind the grill) works in conjunction with the coolant temperature sensor, the A/C high pressure switch, the transmission temperature sender and the PCM. This relay will run the fans from 30% to 99% of full speed based on the signal coming from the PCM. This is all according to the official Chrysler shop manuals that I have for my 2005 Town and Country van.
