The FOB did flash the lights and opened the driver door prior to discovery of the problem. Once I reset the system/s by grounding the battery positive cable to the neg cable, the car no longer recognized the FOB for remote locking and unlocking.
Also, The lock/unlock switch on the center console Does Not lock or unlock the doors now. It did prior to this problem
Nothing has been changed on the car and it has behaved normally since I rescued it about 1 year ago.
It had sat for about a week during our bout with sub zero temperatures. Once it was free of snow is when I unlocked it with the remote and started the car. That was when I noticed that the wipers and turn signals no longer worked and that the remote no longer would lock or unlock the doors.
