Like anything else on the truck, it's something you could tackle yourself if you have the skills and tools to do it. There is a thread someone posted where they added ventilated seats to their truck. And they give details about what they did. Pretty sure others have done it too. You might want to see if you can find it if you want to work on it yourself. I understand your hesitation in letting the dealership fix it, but I'd take it in if it's still under warranty. There's no guarantee I wouldn't mess something up LOL, and I'm sure the parts are not cheap.
