Hello...I need some help...My 2001 RX would not start tonight...had not driven it in 3 weeks....new battery in june 2010....jump started the car but during the jumper cable connection i may have connected the cables incorrectly(i know stupid me working in dark garage at night)...horn/lights came on together as i realized the mistake....i now have charged the battery with a charger BUT no interior lights work, wipers dont work, can't move the shifter out of park.....checked fuses for wipers, dash lights etc and none are blown....Any help appreciated...the most bizarre thing to me is the shifter stuck in park....

Please help!
