Well it turns out my 2004 KC Titans rear speakers aren't working. I bought this truck used about a month ago, and didn't even notice it for about a week. Not only this, but I figured out that everytime I open the rear passenger door to buckle my sons booster seat in the passenger airbag light stays on. I took a look at the wiring harness from the cab to the door and noticed there is a tear with exposed/broken wires showing. Bingo... The seatbelt harness is broken causing the restraint system to throw a code. I have not scanned for the code, but after reading alot off this website I figured it out. I have done the reset to the computer many times with success until this past Saturday. I contacted my local Nissan *stealership* and they said the recall didn't cover my titan. Isn't it strange that Nissan recalled these trucks for a bad harness in the rear doors, Mines broken on both the passenger and drivers door, but the recall doesn't cover my problem. Hmm. I guess my question is, could I just repair these myself? I have several years experiance with wiring, or should I try and fight this?
