I'd recommend you use a circuit tester to check the functions on your 7 way connector. Check each pin as its function is activated. If that checks out you might have a weak ground connection on the vehicle or the trailer side. There should be a secure ground connection to clean metal on both the trailer and the vehicle side of the connector.
