2008 door lock relay help

[stevenfaustin]

Hi all, i recently replaced both rear door lock actuators on my 2008 tahoe. All was fine for a few days but then they randomly stopped working. I found that a 15A fuse (labeled #18 in instrument panel fuse box) keeps burning out. Each time I replace it the rear doors function normally and then the fuse goes out after a few lock/unlock cycles. I think it could be a bad relay? Having trouble actually locating where it is..

There are some more fuses under the steering wheel above the brake pedal. I don't have the schematics handy but they deal with the doors as well

Hi
I suggest you to check the door lock relay
It might has a bad connection

Thanks
