OK I bought this truck used and "everything worked" when I test drove it, a few days after I took delivery I noticed the from seats were not heating, further investigation they are not cooling either. I bought the GAP tool and downloaded the codes this is what I found;
B1231-7A Right and Left Seat failure logged at the same time?? What would cause this? This was the morning before I took delivery, could they have dislodged something detailing the car? Later same day the U0140-00 Lost communication with BCM fault triggered, this was after I took delivery. Both seats not heating or cooling and the dealer swears they were working.....I would like to restore these but the possible $2k bill isnt that attractive....
Hoping this might be a simple fix, cant imagine both seats would crap out at the same time (3 seconds apart...)
