Thank you for clearly describing the issue with the motor on one of your landing gear legs.
When a jack motor operates when there is no load on it but fails to operate when there is a load this usually relates to a loose power connection. Check both of your power leads to that motor to ensure that both ground and hot connections are absolutely tight.
A weak ground will deliver some power but often not enough to lift. When a jack operates in the retract direction but not in the extend direction this too tends to indicate a weak power connection. The motor may function in the "gravity-assisted" retract direction but not in the extend direction when it is having to do the actual lifting, which requires far more current.
