The power door locks on my truck have been acting up lately. That is, they unlock by themselves without me pushing the switch or keyless entry unlock button even with the truck off. I know there is a TSB for this problem (08-023-03) that recommends replacement of the "switch, door lock cylinder" (part numbers 56049285AA and 56049284AA). My dealer tells me that these parts are on backorder and may not be available for many weeks. I searched the Internet but could not find a part with a similar name or part number. I'm getting a little sick of pulling fuse 13 to lock the truck. Any idea where I could find these parts? Thanks in advance.
