I have a 1993 Thunderbird LX 2 dr coupe automatic and it has beeen sitting in my garage for about three months now because i can't get out of park. I turn my car on and it works fine but then i try to put it in reverse and its just stuck. The little button on the side of the shifter knob goes down but the shifter itself just doesnt go down. Also my brake light stays on even when i take the parking brake out of lock position. I had been working on installing a sound system and i had to unhook my batterry but i dont know if that caused the problem. I don't know what is the problem and neither do my freinds. Does anybody know anything that could help me I would greatly appreciate it.
