01 Integra l.s 2dr hatch trunk lock problem

Trunk lock will only open when key is turned and held clockwise. Will not open from inside release switch, also trunk is making a buzzing sound when key is engaged. This is only way trunk will open and there is no remote for this car. Please help or advise. Thank you J.Przystasz

Power hatch motor at fault?

Is there any ‘buzzing’ sound at the hatch when the inside release switch is activated?

Yes, When locks are open and lever is slid to the left.
