Simple job turned into something major, I hope not. 97 corolla, r. rear brake light not working. Replaced the bulb, everything was working good, decided to replace all bulbs, Antie told me she doesn't remember when they were changed. placed all new bulbs, 1157 for brake lights, 1156 for backup lights. Now no brake and parking lights. Signal and hazard lights are working, I wanted to see if the backup lights worked, guess what, the shifter won't move, like it is stuck. Answer: OK in the process you have blown the brake lamp fuse and this also will affect the shift interlock device. so replace the fuse and see if it blows again or not. if not then great, your back on the road, if so then you have a short to ground somewhere in the circuit.
