Gear shift stuck in park

Would you supply me with a diagram of how to remove the center console?

Recently, I am experiencing problems with my gear shift refusing to release from the park position. The first time I experienced this problem, about a week ago, we were able to get the shifter to release after rocking the car back and forth. I have not had another problem until this morning. Unfortunately, I was the only one and had to leave the car there so I am unsure if the same approach would rectify the situation again, if only temporarily.

I park on flat surfaces 98% of the time, the climate is slight cool to warm (lower south of central USA) and I can feel the switch in the gear shift move when the brake is depressed. I also have not experience an issue with the key becoming stuck or inhibited within the ignition. I did not check the brake lights though will do so when I get home and have access to the vehicle.

After reading the other related posts on this site, I feel pretty confident that my issue revolves around that wire located on the driver's side of the center console. I believe it indeed to be the culprit of my troubles since I left the sun roof open for about 36 or so hours during a storm and following within 24 hours of that, my husband spilling an entire soda (very large fast food drive thru size) directly over the center console/ gear shift. I experienced my first trouble with the stuck gear shift within 1-3 days following those events.

I did receive a code this morning stating something about the immobilizer - see manual, but this code never came up again after I turned the ignition off. I look this up in the manual and it stated that it could be the result of a problem with the key no longer working properly and that I would need to obtain a replacement so that some sensor in the ignition would recognize the code imbedded within the key thereby 'allowing the car to start properly'. I think I only received this code because I was jiggling the key back and forth and in and out of the ignition. Like I said, immediately after turning the car off and back on again, the code was gone and never showed up again.

All of this being said, let me say that I am NOT a mechanic nor do I know much at all about repairing and/or servicing an automobile. I leave that up to my husband! Therefore, please let me know if you think this may be related to some other issue with the car.I welcome any and all advice!

Thanks in advance,
