I was replacing bulbs in the center console and removed the climate control/theft module located underneath the nav screen in the 03 ES. I disconnected all three harnesses that plug in the back. I plugged everything back in after I was done and I can't start the car, I do hear the starter clicking though. I had the battery running for a little bit but not long enough to drain the battery IMO (nav/radio/lights everything works fine so I don't think the battery is dead).

I'm wondering if something in the theft system was tripped preventing the car from starting after I disconnected that module?

 

I kind of had this problem. all it took to fix it was use my key on the outside of the drivers side to lock and unlock a couple of times.
