Alright, so for my first post :D

A little background:

I'm currently designing a program on my pc(eventually on android tablet), to control things in the vehicle. Right now I can control the following:
- Passenger window, rear driver and passenger windows, heat up or down, fan up or down, lock/unlock, steering wheel controls...
Other things don't show packets, like the defrost, switching the vents, tuning radio by hand, and the drivers door window... I can't figure out why.. or how to access the drivers door module :\

My question though:

I have an 03 trailblazer, which uses the J1850 VPW (GM's Class2) CAN BUS. The baud rate for this is 10.4k. I can connect and get packets and roll my windows down,etc with my pc and sending the same packets. BUT, I would like to control things with my Arduino. I believe the one wire(pin2) would be the only wire I would need to read from.. Because it's a one wire scan bus system, until GM's later years GMLAN.. Which was a 2 wire high speed, one wire low speed can bus system..What's everyone's opinion? in advance, thank you..

CAN? Tin or aluminum?

Could the door be on a LIN network, perhaps?

How the heck did I end up here?
