Down trim stopped working yesterday. Up is fine. Motor sounds fine, batteries are new. Tried both trim switches on the Center Console and Cowling of the motor. When I do hit the down trim I can hear it click but nothing. I can't seem to find out where exactly the click is but it is coming from the front of the motor. I'm sure it's a relay, but don't know where it is. Can you pls. tell me where to look and what to do to fix this prob.
