The auto door locks on my truck will not lock. You can lock them by hand, and they will unlock with the switch or the key fob. Also, the horn won't work. Any ideas would be appreciated. Keep in mind that this is all 4 doors. I've tested my switches, checked grounds and checked fuses.

Thanks

 

On my Lariat, I can enable/disable the autolock feature in the trip computer. On the horn, Id check the fuse then see if the hord is still hooked up.
