Power door locks not working

[Lantec]

I have a BJ73 and I installed after-market power door locks.

The driver side today stopped unlocking. It'll still lock but when I unlock, it'll stay locked, I can feel some movement but not enough power to push it up..


Would it be a possibility that the actuator is loose and can't push it up or is it along the times of being broken?

K, now it's kinda working but not all the time.

Sometimes it only goes up half way and sometimes it goes up all the way or not at all.. I can see it kinda move up for a split second before dropping back down again

Cant quite see it from here,you might have to pull a door trim off for a better looksy

My guess is it will be low voltage,so check the connections.
Also these aftermarket door locks have an early death rate from my experiences with them
