Both mirrors move automatically when car starts! Driver side moves down and in, passenger side moves out and up. Both motors start making popping noises once they've moved as far as they can for 10-15 seconds. Then I try the switch to move them where they belong but they don't want to cooperate and become useless by going back to the position they went to once the car started. Any ideas what the issue could be?

Thanks in advance,
Bryan
