The battery was weak so charged it, then wouldn't start stating no key-fob , plugged in versus, tried to reset codes, it cleared all fobs , now it wont let me reprogram the fob 1. Also, the drivers door module seemed to have some contamination, so I cleaned it. some thing on car work now but still no power to the fob antenna in the middle console. is there a diagram I can follow to chase wiring or another fuse block i am missing?

Hi and thanks for using 2CarPros.

The first three pictures show pin allocation related to the receiver.

Next, pictures 4 and 5 show the receiver antenna wiring to the remote control module. I highlighted the wires going between the antenna receiver and the module in picture 5.
