I made an appointment with my dealer for next week. Then, I called to confirm that they're going to be able to perform the work. The guy I talked to said "Oh yeah, Y76.. we've been doing those". He said they run a test and if it passes you're good, and if it doesn't pass they call their engineers to see what they want them to do.
On a side note, the recall report lists part number 68444169AA as the involved component (i.e. the grid heater relay). I went outside and looked at mine which has part number 68444169AB. I wonder if this means my truck doesn't have a relay of the spontaneous combustion variety? Is 68444169AB maybe the relay that was used on trucks outside of the recall notice that were produced after 10/8? My truck was made on 9/17, I think.
