Is the relay the problem?\u003c\/summary\u003e\n  \u003cp\u003eThis is a classic symptom of a failed relay. Power trim systems use one or two relays to reverse the motor's polarity. If it operates in one direction, the motor is likely fine, but the relay has failed on one side of its internal switch. Replacing the relay usually solves this.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eIs this a single relay or do I need two?\u003c\/summary\u003e\n  \u003cp\u003eThis depends on your system. Some older or simpler trim systems use a single relay, while many use a pair of identical relays (one for up, one for down). Check your engine's service manual or inspect the existing setup.
