Possible weak door lock fix?

Recommended Posts

After replacing a door lock actulator on my 1999 suburban ($60 at napa) I took my old one apart to find out what went wrong. After some cleaning and testing I found that there is a circuit breaker inside to protect the lock motor that went bad. I then soldered the breaker closed lubed the gears and reassembled. It now seems to have the same or more power than the new one. My question is how does someone determine the size and type of circuit breaker to replace the weak one. I would assume it would require splicing it in to the wires in the door because space is limited inside the actulator but it could be done. Any thoughts would help. Thanks.

Seems like a lot of work just to save the actuator.


You could probably get yourself a circuit breaker that normally plugs into the fuse panel.


The lock actuator by itself probably has maybe a 1 amp draw, so it'd have to be a pretty small circuit breaker. I don't know if you can buy a 1A circuit breaker.
