I have found the issue...20 amp fuse to autozone.

Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.

If the fuse does not help, let me know.

Customer: replied 10 months ago.
The fuse worked for awhile, my assumption is there is a short somewhere. Everything worked until you used the FOB to lock the doors. The drivers door would not lock. Multiple attempts blue the fuse again. Perhaps there is an issue with the driver's door mechanism? I am hoping you have a solution.Brent

If you just use the door lock switch on the door does this cause the fuse to fail?

If so which fuse is failing and in which fuse box.

Customer: replied 10 months ago.
the 20AMP yellow fuse under the dash.

Got anything yet?

Step one is to unplug both door lock actuators inside the door then command the locks locked/unlocked multiple times from both switches with the doors open and closed to see if the fuse fails. If the fuse does not fail then plug in one actuator at a time and retest to see which is to blame. If the fuse did fail during this test then you have a wire short to ground most likely in one of the door jams.

This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.
