My seat switch buzzs and won't raise or lower the front of seat and the seat memory clears when you turn off the key

You may have a bad seat motor or it has something plugging the movement. Make sure everything is clear from the seat. Check the tracks and make sure they are not bent or clogged. If you put in a new switch because of this problem, chances are it may not have been the switch but a burnt out electric motor. Have you made sure all the words are correct and have clean connections? Right now I'd bet on the motor being bad. Common problem with car seats.
