I recently took my Ford Explorer in to be checked due to a fuse that was continually blowing when I used the automatic door locks. The service shop told me that the fuse if blowing because of bad door lock actuators and they are pullijng a highier amperage than the fuse can take in oder for them to operate. I am able to use the locks one or two times after I replace the 30 AMP fuse each time before it blows. The mechanic said that all 5 actuators needed to be replaced. Is it possible that only one of them need be replaced and is there a way I can check to see if any one of them is bad. (Ie. A fairly uncomplicated method to unhook each door lock from the electical circuit one at a time to see if this works.) I figured I would start with the back door lock first but wanted to get your advice. Thanks you for the website and your time!

Hi there,

thank you for your donation.

This can be done, but it is a tricky operation, because the amp draw is such a short duration, you may not get an accurate visual reading using a conventional amp meter. You will need one that holds peak current draw. To get a true reading you would need to get as close to the actuator as possible, but tapping in line will be a pain, You will get a fair indication if you connect an amp meter between the battery Pos(+) and the battery cable, operate the lock and watch for peak current draw, if one spikes higher, there is a starting point, but a meter which holds peak drain memory will be a great advantage.
